PROPOSAL/SUMMARY
On June 22, 1992, the City Council reviewed the Preliminary Plat #92 -5, Rezoning #92 -3, and 1
Wetland Alteration Permit #92 -6 for Bluff Creek Estates and recommended approval of this
application (Attachment #2). 1
The applicant is requesting approval to subdivide a 9.728 acre site into 4 single family lots and
one outlot. This proposal is the second phase of the Bluff Creek Estates subdivision. Phase I 1
was approved by the City Council on August 24, 1992. The entire project will be developed in
four phases. Phase two, which the applicant is seeking approval for, will consist of 4 single
family lots and one outlot. The site is located west of Audubon Road, north of Sun Ridge 1
Subdivision, and south of Ryan's Chanhassen Business Center. Access to the four lots will be
provided via Valley Ridge Place. All of the proposed lots meet or exceed the minimum 15,000
square feet of area with an average lot size of 18,134 square feet. The site was farmed until 1
recently and is devoid of significant vegetation.
Williams Pipe Line Company has a 75 foot wide easement that runs east and west through Lots 1
1 and 2, Block 1. It is city policy, as well as utility companies, not to allow any structure to be
constructed within an easement.
Staff believes that this plat request is a reasonable one and is generally consistent with guidelines

recommendations:
This proposed plat is a replat of a portion of Outlot C of Bluff Creek Estates 1st Addition.
In conjunction with Bluff Creek Estates 1st Addition, utility and street improvements have

I PROPOSAL /SUMMARY
The applicant is requesting approval to subdivide a 61.45 acre site into 78 single family lots.
I This proposal will be developed in four phases. Phase one, which the applicant is seeking
approval for, will consist of 20 single family lots and four outlots. One of the lots (Lot 1, Block
1) will be occupied by an existing home. The balance will be available for new construction.
I The site is located west of Audubon Road, north of Sun Ridge Subdivision, and south of Ryan's
Chanhassen Business Center. Access to the subdivision will be provided by a loop road off
Audubon Road.
1 All of the proposed lots meet the minimum requirement of the Zoning Ordinance with the
exception of Lot 7, Block 3, which has a street frontage of 87 feet. The Zoning Ordinance
I requires a 90 foot frontage. Staff is recommending that the applicant revise the final plat and
provide the required 90 foot frontage.
I The Bluff Creek Estates site was located outside of the MUSA line until the recent MUSA
expansion that was approved by the Metropolitan Council in May of 1991. This area is in the
Bluff Creek Sewer Feasibility Area recently approved by the City Council. Sewer service to this
1 area could be available in the fall of 1992 at the earliest. Water service will also be available.
The applicant is proposing to develop this area in four phases. The first phase would include
1 Lots 1 through 6, Block 1, Lots 1 through 6, Block 2, and Lots 1 through 8, Block 3. The
applicant would like to construct one model home located on Lot 2, Block 1 for the Parade of
Homes, which begins the first week of September. This home is proposed to share the driveway
I with the existing home, until such time when the proposed Valley Ridge Trail South is
constructed.
1 Williams Pipe Line Company has a 75 foot wide easement that runs east and west through the
property. It is city policy, as well as utility companies, not to allow any structure to be
I constructed within an easement.
The majority of this site is farmed and is devoid of vegetation except for a line of elm trees that
I run parallel to the north property line, and some wetland vegetation along Bluff Creek occupying
the westerly portion of the site. Phase 1 of this development will not intrude into any heavily
vegetated area or the wetland.
1 The recently adopted Landscaping and Tree Preservation Ordinance states that all development
located on arterial and collector streets are required to provide streetscape landscaping. The
I landscaping plan which was submitted by the applicant as part of the preliminary plat is in
response to this requirement, and is of a very high quality and exceeds the city ordinance
standards.

There is a wetland on the site. This wetland includes the protected water course of Bluff Creek.
The wetland is not proposed to be altered other than a small portion where a storm sewer outlet
will be located. This area will then be restored to its natural state. The wetland and Bluff Creek
are located within a conservation easement in an outlot.
The Park and Recreation Commission is recommending that park fees be paid in lieu of park 1
land. They are recommending the city acquire ownership of Outlot A. This would allow for
continuation of the Bluff Creek preservation corridor which would ultimately extend from
Minnewashta Regional Park to the Minnesota River.
Staff believes that this plat request is a reasonable one and is generally consistent with guidelines
established by the city's Comprehensive Plan and Zoning Ordinance. We find it to be well
designed with only modest revisions being required. We are recommending that it be approved
with conditions outlined in the report. 1
BACKGROUND
On June 22, 1992, the Ci ty Council reviewed the preliminary plat #92 -5, Rezoning #92 -3, and
Wetland Alteration Permit #92 -6 for Bluff Creek Estates and recommended approval of this
application. 1
FINAL PLAT
The applicant is proposing to subdivide a 61.45 acre site into 20 single family lots and four
outlots. All outlots with the exception of Outlot A are reserved for future single family
development. The density of the proposed subdivision is 1.27 units per acre gross, and 2.3 units
per acre net after removing the wetland and roads. All the lots meet or exceed the minimum
15,000 square feet of area with an average lot size of 18,904 square feet. Lot 7, Block 3, which
has a street frontage of 87 feet is not in compliance with the Zoning Ordinance. The Zoning
Ordinance requires a 90 foot frontage for single family lots. Staff is recommending that the
applicant revise the final plat and provide the required 90 foot frontage.
The western portion of the site containing outlot A is not a buildable lot, and contains Bluff
Creek and an associated wetland. The Park and Recreation Commission is recommending that
the city acquire ownership of Outlot A, allowing for continuation of the Bluff Creek preservation
corridor.
Staff notes that the proposal is consistent with the Comprehensive Plan and generally consistent
with the Zoning Ordinance.

1 Grading and Drainage
The overall site development plan proposes to construct the development in four phases with the
' initial phase proposed as Bluff Creek Estates 1st Addition located in the southeast corner of the
development adjacent to Audubon Road. Included with the site grading is the construction of
two temporary sedimentation basins for treatment of the storm runoff generated from this phase.
The grading plan has been altered per staff's recommendations to minimize runoff towards
Audubon Road.
The street grades within the development have been modified to comply with the City ordinance
of 7% maximum grade. House pad elevations have been revised to fall within the City's
guidelines for driveway grades of less than 10 %. The plans propose a series of storm sewers to
' convey runoff from the development into two temporary sedimentation basins. The basins appear
to be designed in accordance with the Watershed District's best management practice handbook;
however, some additional information is required on the construction plans and will be addressed
1 with the plans and specification review process. Based on storm sewer calculations, it appears
additional storm sewers may be necessary. Staff again will be working with the developer's
engineer to develop a plan to adequately handle the runoff.
Staff still has not received earthwork calculations to determine if the site earthwork balances or
if the site requires imported material or to export. Staff still request this information to determine
1 if appropriate traffic signage will be required or additional financial security requirements are
necessary.
1 Utilities
On July 27, 1992, the Chanhassen City Council approved the construction plans for the Upper
Bluff Creek trunk sewer and water improvements which will service this phase of the
development. The City's project is being phased in an effort to complete a portion of the trunk
' gravity sewer service to service this development. Staff anticipates this segment of the trunk
improvements to be operational sometime in the fall of 1992. The utility construction plans for
Bluff Creek Estates 1st Addition have been reviewed by staff. The plans are generally acceptable
' with some minor modifications which will be worked out between staff and the developer's
engineer. Watermain sizing should be verified by the applicant's engineer. Detailed calculations
demonstrating sufficient fire flow during peak demand should be supplied to the City Engineer
' for review. Final construction plans and specifications have been prepared in conjunction with
this final plat. The overall utility and street construction plans and specifications have been
prepared in general accordance with the City's standard specifications and detail plates subject
1 to minor modifications.

Streets
This phase of the development proposes one access on Audubon Road. The first phase is
scheduled to terminate with a temporary cul -de -sac at the end of Valley Ridge Trail South. A
temporary road easement will be required by the applicant for the temporary cul-de -sac.
This phase of the development does not propose to construct a northerly entrance to the
development (Valley Ridge Trail North). Lot 1, Block 1 contains an existing Chaska brick home
which has a horseshoe driveway with two access points on Audubon Road. Staff and City
Council previously recommended that one access be eliminated with the development. Staff still
supports this recommendation but may defer removal of one of the driveways until the Valley
Ridge Trail North street is constructed. Lot 2, Block 1 should be restricted to access off of the
interior street (Valley Ridge Trail South) only. It is understood that this lot is also being
considered for a model home and the applicant is requesting a temporary entrance from Audubon
Road until the streets are completed in the development. Staff finds this acceptable with the
understanding that the permanent driveway will be from Valley Ridge Trail South when the street
is completed with the first lift of bituminous.
1
Erosion Control
A series of erosion control fences are being implemented throughout the development. Staff has
reviewed the erosion control measures and finds them acceptable.
Miscellaneous 1
On Lot 1, Block 1 the existing Chaska brick home will become within 150 feet of municipal
sanitary sewer. In accordance with the City Code, the house will be required to connect to
municipal sanitary sewer within one year after the sewer has been made available. A sanitary
sewer service stub is being provided with the City's trunk improvement project for this lot. / '
The rear lots within Block 2 drain westerly to a storm sewer catch basin. All the lots with the
exception of Lot 4 contain a 10 -foot backyard drainage easement. It is recommended that a 10-
foot wide drainage and utility easement also be conveyed on the final plat along the northerly
lot line of Lot 4, Block 2.
To insure the temporary sediment basins are maintained and drainage areas protected, it is
recommended that a temporary drainage easement be conveyed to the City for the temporary
ponding areas and storm sewer line to Bluff Creek.

Landscaping
The recently adopted Landscaping and Tree Preservation requirements state that a landscape
Y P P g �1 P
' buffer is required when a subdivision plat is contiguous with a collector street. Required
buffering shall consist of berms and landscape materials consisting of a mix of trees and shrubs
and/or a tree preservation area. The plan identifies plant material locations along Audubon Road
' as well as a single planting (21/2" Norway Maple). Appropriate financial security will be
required.
' The northern edge of the site will be buffered by a 100 foot wide landscaped area from the
Chanhassen Business Center, as designated in the Comprehensive Plan.
Park and Recreation
The Park and Recreation Commission recommended the City Council require full park fees be
paid as a condition of approval of Bluff Creek Estates. Fees to be paid at the time of building
permit approval in the amount of the park fee in force at the time of building permit application.
The final plat identifies the western 19.7 acres of the site as an outlot. This entire area is below
the 100 year flood elevation and will contain a portion of the Bluff Creek Corridor turf trail
identified in the city's Comprehensive Plan. This outlot extends to the east in a bottle -neck
fashion, abutting proposed Valley Ridge Trail South, allowing for pedestrian access from the
residential street. The second trail associated with this site is the proposed Audubon Road off-
street alignment. Through consultation with the city's engineering department, it has been
determined that no additional right -of -way is necessary if this trail is to be constructed west of
Audubon Road.
' The Park and Recreation Commission recommended that the City Council acquire ownership of
Outlot A, allowing for continuation of the Bluff Creek preservation corridor, and require the
' installation of an 8 foot bituminous trail surface from the west edge of proposed Valley Ridge
Trail to outlot A as a condition of approval of this plat. In consideration for this, it is
recommended that the city give full trail fee credit to the applicant.

DATE: August 20, 1992 I
SUBJ: Review of Final Plat for Bluff Creek Estates 1st Addition
1
Project No. 92 -10
Upon review of the final plat, grading, drainage and utility plans prepared by James R. Hill, I
Inc., I offer the following comments and recommendations:
GRADING AND DRAINAGE
The overall site development plan proposes to construct the development in four phases 1
with the initial phase proposed as Bluff Creek Estates 1st Addition located in the southeast
corner of the development adjacent to Audubon Road. Included with the site grading is the
construction of two temporary sedimentation basins for treatment of the storm runoff I
generated from this phase. The grading plan has been altered per staff's recommendations
to minimize runoff towards Audubon Road.
ment have been I
The street grades within the development modified to comply with the City
ordinance of 7% maximum grade. House pad elevations have been revised to fall within
the City's guidelines for driveway grades of less than 10 %. The plans propose a series of I
storm sewers to convey runoff from the development into two temporary sedimentation
basins. The basins appear to be designed in accordance with the Watershed District's best
management practice handbook; however, some additional information is required on the
construction plans and will be addressed with the plans and specification review process.
Based on storm sewer calculations, it appears additional storm sewers may be necessary.
Staff again will be working with the developer's engineer to develop a plan to adequately I
handle the runoff.
Staff still has not received earthwork calculations to determine if the site earthwork balances I
or if the site requires imported material or to export. Staff still request this information to

1 determine if appropriate traffic signage will be required or additional financial security
requirements are necessary.
UTILITIES
I On Jul 27, 1992, the Chanhassen City Council approved the construction plans f
July ty pp pans or the
Upper Bluff Creek trunk sewer and water improvements which will service this phase of the
I development. The City's project is being phased in an effort to complete a portion of the
trunk gravity sewer service to service this development. Staff anticipates this segment of the
I trunk improvements to be operational sometime in the fall of 1992. The utility construction
plans for Bluff Creek Estates 1st Addition have been reviewed by staff. The plans are
generally acceptable with some minor modifications which will be worked out between staff
I and the developer's engineer. Watermain sizing should be verified by the applicant's
engineer. Detailed calculations demonstrating sufficient fire flow during peak demand
should be supplied to the City Engineer for review. Final construction plans and
I specifications have been prepared in conjunction with this final plat. The overall utility and
street construction plans and specifications have been prepared in general accordance with
the City's standard specifications and detail plates subject to minor modifications.
1 STREETS
I This phase of the development proposes one access on Audubon Road. The first phase is
scheduled to terminate with a temporary cul -de -sac at the end of Valley Ridge Trail South.
A temporary road easement will be required by the applicant for the temporary cul -de -sac.
I This phase of the development does not propose to construct a northerly entrance to the
development (Valley Ridge Trail North). Lot 1, Block 1 contains an existing Chaska brick
1 home which has a horseshoe driveway with two access points on Audubon Road. Staff and
City Council previously recommended that one access be eliminated with the development.
Staff still supports this recommendation but may defer removal of one of the driveways until
I the Valley Ridge Trail North street is constructed. Lot 2, Block 1 should be restricted to
access off of the interior street (Valley Ridge Trail South) only. It is understood that this
lot is also being considered for a model home and the applicant is requesting a temporary
I entrance from Audubon Road until the streets are completed in the development. Staff
finds this acceptable with the understanding that the permanent driveway will be from
I Valley Ridge Trail South when the street is completed with the first lift of bituminous.
EROSION CONTROL
I A series of erosion control fences are being implemented throughout the development. Staff
has reviewed the erosion control measures and finds them acceptable.

MISCELLANEOUS
On Lot 1, Block 1 the existing Chaska brick home will become within 150 feet of municipal
g
sanitary sewer. In accordance with the City Code, the house will be required to connect to
municipal sanitary sewer within one year after the sewer has been made available. A
sanitary sewer service stub is being provided with the City's trunk improvement project for
this lot.
1
The rear lots within Block 2 drain westerly to a storm sewer catch basin. All the lots with
the exception of Lot 4 contain a 10 -foot backyard drainage easement. It is recommended
that a 10 -foot wide drainage and utility easement also be conveyed on the final plat along
the northerly lot line of Lot 4, Block 2.
To insure the temporary sediment basins are maintained and drainage areas protected, it
is recommended that a temporary drainage easement be conveyed to the City for the
temporary ponding areas and storm sewer line to Bluff Creek. '
RECOMMENDED CONDITIONS OF APPROVAL
1. All utility and street improvements shall be constructed in accordance with the 1
current edition of the City's Standard Specifications and Detail Plates. Detailed
street and utility construction plans and specifications shall be submitted for City
Council approval.
2. The applicant shall apply for and obtain permits from the Watershed District, DNR
or other appropriate regulatory agencies in comply with conditions of approval.
3. The watermain system shall be designed to insure adequate fire flow protection for

other properties. Is the dock setback, does it have to ue specified? Is it
just a city ordinance that's going to be enforced? Where do we stand on that?
Paul Krauss: Roger gave us a reading on that.
Mayor Chmiel: That was last time. ,
Paul Krauss: Whether it's applicable after the fact.
Roger Knutson: As you know I'm preparing, I finished the draft today of ,
revisions on the dock setback ordinance. All we're doing today is defining what
was there in 1932. ...modifying it. Not saying it's good, bad or indifferent
or anything else. Here's what was there in 1982.
Councilwoman Dimler: So I'm also understanding that that includes all the other
Planning Commission recommendations as well in this same motion? '
Paul Krauss: Yes.
Councilwoman Dimler: The canoe rack, the two docks, the boat launch, the '
portable toilet and the milfoil sign.
Mayor Chmiel: Yes. ,
Councilman Mason moved, Councilman Workman seconded to approve the
Non - Conforming Recreational Beachlot Permit for Pleasant Acres Homeowners
Association to include motor vehicle access, off street parking for 10, one boat
launch, two seasonal docks (96' x 67' and 96' x 12'), one canoe rack, 10 boats
docked, swimming beach, marker buoys, swimming raft, 7 power lifts and a

(�- C. WETLAND ALTERATION PERMIT FOR CONSTRUCTION WITHIN 200 FEET OF A WETLAND.
a , l
P Sharmin Al -Jaff: The applicant is requesting to subdivide a 61.45 acre site
into 78 single family lots. Access to the subdivision will be provided by a
looped road off of Audubon Road. It is proposed to be developed in four phases.
All of the proposed lots meet the minimum requirements of the Zoning Ordinance
with one exception. Lot 8 has an existing garage. The proposed rear property
line is setback at 20 feet from the garage. The ordinance requires a 30 foot
setback. The Planning Commission was strongly opposed to a variance to the rear
yard setback and they recommended that the applicant adjust the property line to
eliminate this variance. There is a wetland on this site. The wetland includes
the protected water of course of Bluff Creek. It is contained within Outlot A.
The applicant is not proposing to disturb this wetland. However, out ordinance
requires any development within 200 feet to receive a wetland alteration permit.
We are recommending approval of the wetland alteration permit with conditions
outlined in the report. The applicant is also requesting to rezone the property
21 1
City Council Meeting - June 7', 1992
II t
from A2 to Residential Single Family. This is consistent with the
Comprehensive Plan. We are recommending approval of the rezoning. There is one
II issue that was brought up at the Planning Commission and we would like to bring
it to your attention as well. There is an existing driveway on the site. It's
in the shape of a horseshoe. Staff had recommended that this driveway be
II eliminated. It accesses off of Audubon road. We also recommended that access
to Lot 8 would be through Lot 7 so that would require a cross access easement.
The applicant requested that he maintain his existing driveway. A couple of
issues with that is one, we have some safety concerns. Second issue is the
driveway will be encroaching onto the deceleration lane. Charles might want to
elaborate further on that. Other than that, we are recommending approval of
this application with conditions outlined in the report.
II Mayor Chmiel: What is that distance from the existing driveway to the proposed
road that will go in?
II Sharmin Al -Jaff: I'm sorry Mr. Mayor.
Mayor Chmiel: What is the distance between the driveway and the road? How many
II feet?
Sharmin Al -Jaff: It's approximately 200 feet.
II Mayor Chmiel: What's the distance requirements between one point to the other
Charles without it causing any problems? The sight lines.
II Charles Folch: Well, the City has no ordinance governing the spacing of
driveways as say for example Carver County would have. In general we would
typically use MnOot's standards for, or based on the design speed of the road,
I for spacing of intersections. What the critical situation here is that for the
two entrances into the subdivision, we're proposing to construct right turn
lanes into the subdivision and what you end up having with the driveway there is
II you have a driveway coming out which will access right basically in the taper
section of the turn lane. While this is not an ideal situation, it's not
unique. These situations do occur on other rural type highways. In general we
would prefer not to see it but it's something we could work around if it came
down to that.
Mayor Chmiel: Okay with speeds that are existing now, was that 50 in there now?
II Charles Folch: It's 50 at that portion of the roadway.
Mayor Chmiel: As the area progresses and more residential goes in, will that
continue to be that speed limit there?
II Charles Folch: Probably not. It will probably get downgraded to either 40 or
45 mph.
Councilwoman Dimler: I had a question on the sight line. It runs east and west
I there pretty much through the property and I don't know how deep it is. But I
II also know that you're not supposed to put a structure on top of the pipeline?
Sharmin Al -Jaff: Correct.
I

I
City Council Meeting - Tune 22, 1992 . ' 11
Councilwoman Dimler: I saw that a portion of the road does cover it. That Road
E. II
Sharmin Al -Jaff: They allow roads, sidewalks to go over the pipeline. It is 3 II feet deep.
Mayor Chmiel: Their main concern basically with Williams Pipeline is that
there's not weight distributed on top because then that causes reactions down II below and could...
Councilwoman Dimler: That won't be a problem in the future then itself?
II
Mayor Chmiel: It should not.
Sharmin Al -Jaff: I called and asked them and they said they had no problems
II
with that.
Mayor Chmiel: Is there anyone from the subdivision that would like to discuss
II
this? Just please state your name and who you're representing and your address
please.
' Jim Hill: Your Honor. My name is Jim Hill. I'm a consultant for Keyland and
II
the fee owner, Rod Grams. Principle is Dick Schuller is here with us this
evening. The petitioner has agreed with the recommendations of staff and the
Planning Commission recommendations with the exception of the driveway. We I
talked to staff and we are in agreement to connect the acceleration and the
deceleration lane in front of and between the two accesses off of Audubon so
that the driveway, assuming that, although Mr. Grams would like both of them
II
left as is, he can see that one would have to be taken out. The northerly one,
which is to the right on the picture there. And that the existing driveway to
the historic home, which Mr. Grams has been asked to keep because of the II architecture and also the Chaska brick. He would like to and he's selling that
on the basis of the two lots. There will not be two lots there. There will be
one because the real estate and marketplace has indicated that the historic home
and it's setting needs the driveway. Should have the driveway that has always II existed and the larger lot. So the two lots will be combined into one. So that
there would be an additional lane then inbetween the two openings off of Audubon
in which then that one driveway would enter. He is asking for at least that in II the preservation of the site. Thank you.
Mayor Chmiel: Thank you. Any discussion? Michael.
Councilman Mason: I say let them keep the driveway. I understand the City II
Engineer's position but like Charles said, they're already out there and clearly
it sounds to me like the speed limit's going to be getting lowered on that road
II
in a matter of years anyway. There is certainly something to be said for the
historic preservation. Other than that I'm fine with it. I'm a little
concerned. What's your client's feeling about not, I think I missed that about II the variance for the shed. Are they willing to adjust the lot line?
Jim Hill: Your Honor, we have looked at the lot line and we will adjust it...
Councilman Mason: That's about all I have on it. '
23 II
II
City Council Meeting - Jur- 22, 1992
Mayor Chmiel: Thank you. Tom.
II Councilman Workman: Yeah, the two issues are the roadway and setback, right?
Mike and I were both talking about it. Mike ended up saying what I thought he
1 was going to say about, big deal. Was that your comment?
Councilman Mason: Well kind of.
I Councilman Workman: But you know the same thing with me. We're not talking
about a whole lot of trips. The darn access has been there forever. Granted
there hasn't been two, one to the north and one to the south that close but I
I don't, and I can't get worried about that and if they move the lot line, then
great.
Councilman Wing: I concur with Tom and Mike and I think preservation of what
II
they have there is...That's part of our historic background. I guess I really
have no comment because this is all up front and it's by the rules in effect.
If I could just whine slightly to say, we pat ourselves on the back and we cheer
1 when we moved the MUSA line and we opened up 3,000 acres for development as if
the land couldn't be developed if we hadn't done it. But by opening it up,
everything that comes before me is this mass of little lots and mass of rows and
II mass of houses and ohhh. I say what are we doing. So it's wonderful we opened
this up but it's all coming back this way. Now this is standard subdivision and
this, now Paul. Don't look that way. I just couldn't resist. Was a PUD
considered and was there any advantages to a PUD?
I Paul Krauss: No not really on this site. Early on when we first met there was
a question of using PUD to reduce lot sizes below 15,000. I told them that that
I really wasn't appropriate. You're talking about a site really that does not
have a whole lot of character.
II Councilman Wing: Yep, I agree. The lots are larger.
Councilwoman Dimler: I concur with the drive. Keeping the driveway and I'm
glad to see that they'll adjust to avoid a variance situation. I'm also
I wondering if they could adjust to avoid the wetland alteration permit. Could
you comment on that?
I Paul Krauss: I think what we really have to do is adjust the ordinance so it
doesn't require one. They're not in the wetland. They're only near one and our
ordinance is a little strange on that.
II Councilwoman Dimler: So it's our ordinance problem, not the problem with the
lot configuration?
I Paul Krauss: Not only are they not going to be in there, but they're dedicating
it all to the city anyway.
II Councilwoman Dimler: Good. I have no problem then.
Councilman Mason: I'd just like to make a quick comment if I could about the
landscaping. It's always refreshing to see people doing more than they need to
I
to make something look nice like that. Thank you. Thanks.
II 24
City Council Meeting - June 22, 1992
L 'I
Mayor Chmiel: I went through this quite readily and there's variation of all
different sized lots and I came up with, I might have missed one but about 9
that only are at 15,000 square feet. All the rest are over and above and many
with 27,000. Some were 29,000. Some that are, I believe that was probably
pretty close to being the largest. But the overall, no there was one. It was
35,000 and that was the biggest but in looking at this I came up with 9 of those
that were 15,000 square feet which I felt was very well done. I think it will
prove to be a good development for it. There's one question that I had left.
The outlot. What size acreage was that? Do you have any idea? 19 acres. Okay.
Just for my own concern. Other than that I guess I don't have any real concerns
with what's going in and I think that it will prove to be beneficial. Richard.
Councilman Wing: Just one quick question. Paul, just for my anxiety level, can
I just assume that everything that occurs within the MUSA line boundary from
this day on are going to be 15,000 foot square lots or smaller in PUD? I mean
is that just fact? 1
Mayor Chmiel: That's by ordinance, 15,000.
Councilman Wing: No, no, minimum. Can I just assume they're going to be 15,000 1
foot subdivisions or PUD's slightly smaller? I mean that's pretty much
financially what's going to dominant?
Paul Krauss: I think you can expect that but I think the Mayor made a very good
point here. That out of the 70 lots, 9 of them were at the minimum.
Councilman Wing: No, I like this one. 1
Paul Krauss: And above that. Again, I mean they're making a silk purse out of
a sows ear a little bit here. I mean you've got a green space that's being
dedicated. They're adding a lot of landscaping to basically a soybean field.
When you're dealing with much more rolling terrain with more wetlands and trees,
the lots tend to be a lot bigger than that anyway. 1
Mayor Chmiel: Okay with that I'd like to request a motion for each one
separately. The first one I'll request is a rezoning from A2 to RSF, 92 -3 and
with the two conditions contained.
Councilman Wing: Mr. Mayor, I'll so move as stated by yourself.
Councilwoman Oimler: Second.
Councilman Wing moved, Councilwoman Disler seconded to approve Rezoning 192 -3 11 property A -2 to RSF with the following conditions:
1. The applicant shall enter into a development contract containing all of the
conditions of approval for this project and shall submit all required
financial guarantees. The development contract shall be recorded against
the property.
2. The applicant shall meet all conditions of the Subdivision #92 -5 and Wetland

1 PROPOSAL /SUMMARY
The applicant is requesting approval to subdivide a 61.45 acre site into 78 single family lots.
I One of the lots will be occupied by an existing home. The balance will be available for new
construction. The site is located west of Audubon Road, north of Sun Ridge Subdivision, and
south of Ryan's Chanhassen Business Center. Access to the subdivision will be provided by a
1 loop road off Audubon Road.
I All of the proposed lots meet the minimum requirement of the Zoning Ordinance with one
exception. Proposed . Lot 8, Block 2 is occupied by the existing residence and a garage.
Presently, access to this site is gained from Audubon Road. The garage will be located
I approximately 20 feet from the rear property line. City ordinances require that any detached
accessory structure in excess of 400 square feet maintain a distance of 30 feet from the rear
property line. The garage has an approximate area of 900 square feet. Mature maple trees
I separate the existing garage from proposed Lot 5, Block 2, creating a natural buffer. We find
this intrusion into the rear yard setback acceptable, and recommend approval of the rear yard
setback variance for the garage. The Planning Commission was strongly opposed to the rear
I yard setback variance, and recommended that the applicant adjust the property lines to
eliminate the variance.
I The Bluff Creek Estates site was located outside of the MUSA line until the recent MUSA
expansion that was approved by the Metropolitan Council in May of 1991. This area is in the
Bluff Creek Sewer Feasibility Area recently approved by the City Council. Sewer service to this
I area could be available in the fall of 1992 at the earliest. Water service will also be available.
The applicant is proposing to develop this area in four phases. The first phase would include
I Lots 8 through 13, and Lots 18 through 23, Block 2, and Lots 18 through 25, Block 3. The
applicant would like to construct one model home located on Lot 9 of Block 2 for the Parade of
Homes, which begins the first week of September. This home is proposed to share the driveway
I with the existing home, until such time when the proposed street to the south of Lot 9 is
constructed.
1 Williams Pipe Line Company has a 75 foot wide easement that runs east and west through the
property. It is city policy, as well as utility companies, not to allow any structure to be
I constructed within an easement. Staff questions the design of two lots that abut the pipe line
easement (Lots 10 and 14, Block 2) due to limitations on the buildable area imposed by the
easement. Staff is recommending that the applicant demonstrate how a house and a deck could
I be placed on these parcels without a variance. The applicant has submitted a model which
he plans on building on the subject lots. The house pad fits comfortably on these lots with
room for deck (See attachment #10).

The majority of this site is farmed and is devoid of vegetation except for a line of elm trees that
run parallel to the north property line, and some wetland vegetation along Bluff Creek occupying
the westerly portion of the site. Staff is recommending conservation easements to preserve these
areas. Tree preservation is a part of the proposed landscaping package.
The recently adopted Landscaping and Tree Preservation Ordinance states that all development 1
located on arterial and collector streets are required to provide streetscape landscaping. The
landscaping plan submitted by the applicant is in response to this requirement, and is of a very
high quality and exceeds the city ordinance standards.
There is a wetland on the site. This wetland includes the protected water course of Bluff Creek.
The wetland is not proposed to be altered, and is within a conservation easement in an outlot.
The Park and Recreation Commission is recommending that park fees be paid in lieu of park
land. They are recommending the city acquire ownership of Outlot A. This would allow for
continuation of the Bluff Creek preservation corridor which would ultimately extend from
Minnewashta Regional Park to the Minnesota River. The installation of an 8 foot bituminous
trail surface from proposed Road E to the rear of Lot 1, Block 1 and Lot 1, Block 3, where it
would provide access to the future trail, is also being recommended. In consideration for this,
it is recommended that the city give full trail fee credit to the applicant.
1
Staff believes that this plat request is a reasonable one and is generally consistent with guidelines
established by the city Comprehensive Plan and Zoning Ordinance. We find it to be well
designed with only modest revisions being required. We are recommending that it be approved
with conditions as outlined in the report.
PRELIMINARY PLAT
The applicant is proposing to subdivide a 61.45 acre site into 78 single family lots and one
outlot. The density of the proposed subdivision is 1.27 units per acre gross, and 2.3 units per
acre net after removing the wetland and roads. All the lots meet or exceed the minimum 15,000
square feet of area with an average lot size of 18,904 square feet.
The western portion of the site contains an outlot. This outlot is not a buildable lot, and contains
Bluff Creek and an associated wetland. The Park and Recreation Commission is recommending
that the city acquire ownership of Outlot A, allowing for continuation of the Bluff Creek
preservation corridor.
Staff notes that the proposal is consistent with the Comprehensive Plan and generally consistent
with the Zoning Ordinance.

Streets /Access
On September 14, 1987, the City Council approved the final plat request for Sun Ridge
subdivision located south of the proposed Bluff Creek Estates Subdivision. It was staff's
1 intention then to recommend that Sun Ridge Court be constructed with a 60 foot easement
reserved at the north of the radius of the cul -de -sac to provide future connection and access to
the property to the north (proposed Bluff Creek Estates). This would have been the ideal street
1 design, however, the 60 foot right -of -way easement was never acquired. It was discussed in the
staff report, but the developer failed to convey it. Since the property has all been sold, there is
little possibility of obtaining the necessary easements without condemnation.
1 Plans for Bluff Creek Estates propose a loop street with two access points on Audubon Road.
The access points appear to be well located to accommodate future extension east of Audubon
I Road when development occurs on these lots. It appears the sight distance of the southerly
access is acceptable based on MnDOT's standards. The right -of -way is proposed at 60 feet
which is the city's urban standard. It is assumed the streets will be constructed to the city's
1 standard at a 31 -foot wide back -to -back street section. Street grades are not provided on the .
ins, however, based on contours, it appears the majority of the street grade will be under the
% maximum grade per city ordinance, except in the area in front of Lots 24 and 25, Block 2.
1 It is recommended the applicant's engineer look at the grades to see if they can be reduced to
meet the city's ordinance. If the street grade is not able to be reduced, a variance will be
required. Staff feels confident that street grades could be negotiated to fall within the city's
1 guidelines.
According to the Eastern Carver County Transportation Study, Audubon Road is classified as a
1 collector class I street. It currently has a 66 foot wide right -of -way, but a 100 foot wide right -of-
way is ultimately required. The preliminary plat proposes dedication of an additional 17 feet of
1 right -of -way to the existing 33 feet, together with an additional 20 foot drainage and utility
easement to facilitate trunk sewer and water improvements the city has proposed along Audubon
Road. Remaining right -of -way would be acquired when parcels to the east are platted.
1 Proposed Lot 8, Block 2, contains an existing "Chaska Brick" house and a garage. Presently, the
horseshoe driveway for this house accesses onto Audubon Road. The garage is located
1 approximately 20 feet from the rear property line and faces north. It is recommended that access
to Audubon Road be eliminated for traffic safety reasons, and Lots 7 and 8, Block 2, share a
driveway off of the northerly loop street (Road E). A driveway cross access easement would
1 then be required across Lot 7, Block 2. Notice of the cross access easement should be placed
in the chain -of -title for Lots 7 and 8, Block 2. This is an effort to reduce the amount of access
points accessing on Audubon Road. The Planning Commission felt that it may be
1 appropriate for the character of the property to have a driveway of some kind going out
to Audubon Road if it was acceptable from a safety standpoint and agreeable with
Engineering Department. Engineering staff has prepared drawings showing the acceleration
1

and deceleration lanes on Audubon Road. The driveway encroaches onto the proposed
lanes and is not desirable from Engineering's view point as it could cause a safety issue (See
attachment #9).
The applicant would like to construct one model home to be located on Lot 9, Block 2 for the
Parade of Homes, which begins in the first week of September. This home is proposed to share
the driveway with the existing home until such time when the proposed street to the south of Lot
9 is constructed. It should be pointed out that Lot 9, Block 2 should also gain its driveway
access off of the interior street (Road E) and not Audubon Road.
The southerly road access proposes an island barrier at Audubon Road. This island should be
I
removed. If the applicant is interested in having an entrance monument, we recommend that it
be placed along the adjacent lot's corner.
Audubon Road is constructed to rural standards with 24 -foot wide bituminous surface and six
font gravel shoulders. North of Heron Drive, Audubon Road has been recently reconstructed into
t wide urban section with concrete curb and gutter and a trail system along the east side.
- pated that in the near future, Audubon Road may be upgraded to urban standards as
_nt pressures warrant upgrading. The applicant should be aware that this development 1
,..,stain some of the costs from the upgrading project in the way of special assessments.
As the final plat is prepared, detailed utility and street construction drawings should be submitted
to the City for review and formal approval. The roadway should be designed to the city's urban
standards.
The plat proposes development to take place in four phases. This phasing includes the street 1
construction as well. Phase one will include a portion of the south quarter of Road E, and all
of Road D. A temporary cul-de -sac should be constructed at the end of the first phase of Road
E until the road can be extended in the future. A sign should be placed on the barricades
indicating the future connection. Notice of the ultimate street extension should be placed in the
chain -of -title for the lots located in this vicinity. All road right -of -way should be platted in the
first phase.
The city's trunk sewer and water improvement project will include construction of an 8 foot
sidewalk along the west side of Audubon Road.
The Fire Marshal is recommending that the street names be approved by Public Safety.

Landscaping and Tree Preservation
The recently adopted Landscaping and Tree Preservation requirements state that a landscape
Y P P g �! P
buffer is required when a subdivision plat is contiguous with a collector street. Required
Bluff Creek Estates
June 3, 1992
Page 6
' buffering shall consist of berms and landscape materials consisting of a mix of trees and shrubs
and/or a tree preservation area. The plan identifies plant material locations along Audubon Road
as well as a single planting (21/2" Norway Maple). Appropriate financial security will be
required.
The Landscaping and Tree Preservation requirements state that it is the policy of the city to
preserve natural woodland areas throughout the city, and with respect to specific site development
to retain as far as practical, substantial tree stands which can be incorporated into the overall
1 landscape plan. Mature elm trees are located along the north edge of the site. There are also
some oak trees. The applicant is proposing to preserve these trees by limiting grading in those
' areas.
Trees designated for preservation shall be protected by snow fence or other means acceptable to
' the city. Protective measures must be located at or beyond the ground foot print of the tree's
crown. No fill material or construction activity shall occur within these areas. These measures
must be in place and inspected prior to the start of grading activity. At the city's discretion,
' conservation easements may be required to protect designated tree preservation areas.
Staff is recommending that a conservation easement be established to protect trees located along
' the north property line of the site. This would be accomplished by designating the conservation
area on the plat and through financial guarantees to ensure that the integrity of the easement is
maintained. Individual lots will be required to show the conservation easement on the plat. Staff
' is also recommending that a tree survey be submitted so that even those tress outside the
conservation easement may be saved as much as possible (Sheet 3 of 5). The applicant is
intending to save some trees on Lots 1, 2, 3 and 5, Block 2, but staff does not believe that would
be possible due to location of future homes.
The northern edge of 'the site will be buffered by a 100 foot wide landscaped area from the
1 Chanhassen Business Center, as designated in the Comprehensive Plan.
Grading/Drainage
' The overall development is proposed to be constructed in two phases with the initial phase
proposed along the easterly portion of the site adjacent to Audubon Road. Ultimately, the entire
site will be regraded along with construction of two retention ponds along the westerly edge of
the property. Since the retention ponds are located in the far westerly portion of the site (Phase
II), the initial phase should provide for an interim or temporary retention ponding to address
1 water quality issues and fulfill the city's storm water retention ordinance. The plans do not
reflect any interim ponding or sediment basins and it is assumed that the applicant will not be
constructing the entire storm sewer at this time. Therefore, it will be necessary for the applicant
to provide interim ponding with Phase I of this development.
1
. '1
Bluff Creek Estates 1

I
The first phase of construction proposes grading the rear lots adjacent to Audubon Road to drain
southerly along Audubon Road to Bluff Creek. Audubon Road currently exists as a rural type
roadway with a ditch section. Any increase in the amount of runoff will create additional
turbulence and potential erosion problems downstream. It is recommended that the applicant's
engineer redesign and raise the lot grades to minimize the amount of runoff towards Audubon I
Road. Eventually, Audubon Road will be upgraded to urban street standards with concrete curb
and gutters similar to just north of the site adjacent to Lake Susan Hills West 3rd Addition. It
would seem prudent to grade the lots adjacent to Audubon Road to be conducive with future I
urban design standards, i.e. eliminate ditch section, build rear yards up to drain out to interior
street (Road "E ") where practical.
Street grades are not shown on the plans based on contours; however, they appear to be 1
acceptable except along Lots 25 and 26, Block 2. The street grades in front of these lots appear
to exceed the city's ordinance of 7.0% maximum grade. Therefore, a variance may be required 1
unless the developer's engineer redesigns the street grade to fall within the city's guidelines of
0.50% to 7.0% grade. Staff believes this can be achieved. The proposed house pads in this same
area are approximately six feet above the street grade which equates to approximately 13% to
I
15% driveway grade which is extremely steep. Typically, the city requires that driveway grades
not to exceed 10 %. It is recommended that the developer's engineer redesign and lower these
lots so the driveway grades do not exceed 10 %.
1
Storm runoff generated from streets and lawns is proposed to be conveyed overland via surface
drainage to a series of storm sewers which will convey runoff into two retention ponds. The 1
applicant's engineer should submit design calculations for the storm sewer and retention ponds.
Storm sewers should be designed for a 10 -year storm event and retention ponds shall retain the
difference between the pre - developed and developed runoff rate for a 100 -year single storm 1
event. The outlet of the pond shall be designed to restrict the discharge to the pre - developed
runoff rate. Ponds shall also be constructed to "NURP" standards to improve water quality.
As part of Phase I construction, no storm sewer improvements are proposed to be constructed. I
P � P P P
Road E becomes a very long street with no storm sewers. It is recommended that the applicant's
I engineer provide an interim retention or sediment pond and storm sewer plans to deal with street
and lawn runoff.
Staff recommends the applicant supply earthwork calculations to the city to determine if the site I
earthwork balances, or if the site requires material to be imported or exported. Staff requests this
information to determine if appropriate traffic signage will be required or if additional financial 1
security requirements are necessary.

Utilities
1 Municipal sanitary sewer and water sewer currently is not available to this site. However, the
city has authorized preparation of plans and specifications to extend trunk sanitary sewer and
' water facilities down along the west side of Audubon Road which will service Phase I of this
site. Phase If of the development will be serviced via a gravity sewer line from a proposed trunk
sanitary sewer which the city will be extending north from Lyman Boulevard adjacent to Bluff
' Creek. The applicant will have to cross over Bluff Creek in the future to extend sewer service
to Phase II. Depending on the city's trunk improvement project's scope and time frame, the
utility line may or may not be operational by October, 1992. The city's project will include
' special assessments for both trunk and lateral sanitary sewer and watermain service to this
development. The preliminary plat is dedicating sufficient right -of -way and utility easements for
installation of the city's trunk sewer and water lines.
1 The utility layout proposed on the utility plan sheet is fairly well laid out. Hydrant spacing may
be of concern to the Fire Marshal and require additional hydrants. The Fire Marshal's rule of
' thumb for hydrant spacing is typically 300 feet apart. There are some areas that exceed this
limitation and will need to be modified. Watermain sizing is not given on the preliminary plans
and should be evaluated by the applicant's engineer. Detailed calculations demonstrating
' sufficient fire flow during peak demands should be supplied to the City Engineer for review.
Final construction plans may be prepared in conjunction with the final platting process. Utility
and street construction plans and specifications shall be prepared using the city's most recent
1 edition of "City Standard Specifications and Detail Plates."
In addition, in the same area, the proposed house pads are approximately six feet above grade
1 which equates to approximately 13% to 15% driveway grade which is extremely steep.
Typically, the city requires the driveway grades not exceed 10 %. It is recommended that the
developer's engineer redesign these lots so the driveway grades do not exceed 10 %.
Storm runoff enerated from streets and lawns is proposed to be conveyed through overland
g P P Y g
surface drainage and a series of storm sewers which discharge into two retention ponds. The
' applicant's engineer shall submit design calculations for the storm sewer and retention ponds.
Storm sewers should be designed for a 10 -year storm event and retention ponds shall retain the
' difference between the pre - developed and developed runoff rate for a 100 -year storm event. The
outlet of the pond shall be designed to restrict the discharge to the pre - developed runoff rate.
Ponds shall also take on water quality characteristics as developed by NURP standards.
1 Erosion Control •
' Plans propose erosion control along the westerly, northerly, and southeasterly property lines. It
is recommended that the proposed erosion control fence be the city's Type III along the wetlands
(Phase II construction) and Type I silt fence along the north and southeasterly portions of the
1
.f
Bluff Creek Estates 1

1
development (Phase I construction). Additional erosion control fence should be installed on Lots
7, 14 and 15, Block 3 as check dams, as well as, Lots 8, 10 and 11, Block 1. The side slopes
along the rear of Lots 1 through 5, Block 3 are steep, approximately 3:1. It is recommended that
an erosion control blanket be used on slopes 3:1 or greater throughout the development and that
all disturbed areas be seeded within two weeks after grading unless MNDOT's planting season
dictates otherwise.
Miscellaneous
1
- The preliminary plat proposes 15 -foot wide drainage and utility easements over the storm sewer
lines proposed along the interior lot lines of the development (outside street right -of -way). It is
I
recommended that the 15 -foot wide easement areas be increased to 20 feet wide to ensure
adequate room for access and maintenance vehicles. The preliminary plat also dedicates a
drainage easement over Lots 7, 8, 10 and 11, Block 1 for a rear yard drainage Swale. Staff
I
recommends that the drainage easement also be extended to include Lots 12 and 13, Block 1.
Easements
1
On the final plat, the following easements and right -of -way shall be indicated:
1. Dedication of all street right-of-way. '
2. Conservation and drainage easements over all protected wetland and ponding areas. 1
Provide access easements to allow the city to maintain all ponding areas.
3. A 20 foot wide utility and drainage easements over all sewer, water, and storm sewer 1
lines located outside public right -of -way.
4. Conservation easements over all designated tree preservation areas. 1
5. Standard drainage and utility easements along each lot line.
I
6. Dedication of Outlot A to the City.
Park and Recreation
The Comprehensive Plan identifies the majority of the site as lying within the service area of
I
Power Hill Park, and as being on the service area fringe of Sunset Ridge Park, and the new park
acquired in Stone Creek. However, the railroad alignment to the north, Audubon Road to the
east, and a lack of trail and street connections present barriers to free access to these parks (see
I
Attachment 2).

Trails which are identified by the Comprehensive Trail plan in the area of Bluff Creek Estates
are depicted on Attachment #2. Two north/south corridors are identified on or abutting to this
' parcel. They are the Bluff Creek drainage turf trail, and the Audubon Road off - street bituminous
alignment.
1 The Park and Recreation Commission recommended the City Council require full park fees be
. paid as a condition of approval of Bluff Creek Estates. Fees to be paid at the time of building
permit approval in the amount of the park fee in force at the time of building permit application.
' The preliminary plat identifies the western 19.7 acres of the site as an outlot. This entire area
is below the 100 year flood elevation and will contain a portion of the Bluff Creek Corridor turf
trail identified in the city's Comprehensive Plan. This outlot extends to the east in a bottle -neck
' - fashion, abutting proposed Road E, allowing for pedestrian access from the residential street. The
second trail associated with this site is the proposed Audubon Road off - street alignment.
Through consultation with the city's engineering department, it has been determined that no
1 additional right -of -way is necessary if this trail is to be constructed west of Audubon Road.
The Park and Recreation Commission recommended that the City Council acquire ownership of
' Outlot A, allowing for continuation of the Bluff Creek preservation corridor, and require the
installation of an 8 foot bituminous trail surface from proposed Road E to the rear of Lot 1,
l :,:ok 1 and Lot 1, Block 3 as a condition of approval of this plat. In consideration for this, it
1 is recommended that the city give full trail fee credit to the applicant.
Rezoning
The applicant is proposing to rezone the property from A -2, Agricultural Estate to RSF,
Residential Single Family. The area to the east and west are zoned A -2. Sun Ridge Subdivision
1 to the south is zoned RR, Rural Residential. The property is bordered on the north by the
recently rezoned PUD by Ryan Construction for the Chanhassen Business Center.
1 The 2000 Land Use Plan shows this area designated for development as Low Density Residential,
1.2 - 4.0 units per acre. The applicant's proposal has a gross density of 1.27 units per acre and
' 2.3 units per acre net after the streets and wetlands are taken out.
This area is in the new MUSA area. The sewer service will be from the new Bluff Creek service
' area system. The feasibility for this sewer and timing was recently approved by the City
Council. At the earliest, sewer could be available to this site in late fall.
' Staff is recommending that this area be rezoned to RSF and the rezoning is consistent with the
Comprehensive Plan.

* Variance required: Proposed Lot 8, Block 2, contains an existing "Chaska Brick" house and I
a garage. Presently, the driveway for this house accesses onto Audubon Road. The garage is
located approximately 20 feet from the rear property line and faces north. City ordinances
requires any detached accessory structure in excess of 400 square feet to maintain a distance of I
30 feet from the rear property line. The garage has an approximate area of 900 square feet.
Mature maple trees separate the existing garage from proposed Lot 5, Block 2, creating a natural
buffer. We find this intrusion into the rear yard setback acceptable and recommend approval of I
the rear yard setback variance for the garage. The Planning Commission was strongly opposed
to the rear yard setback variance and recommended that the applicant adjust the property
lines to eliminate the variance.
I
WETLAND ALTERATION PERMIT
The site contains a Class A wetland according to the Department of Interior Wetland Inventory 1
Map. The area of the wetland is approximately 19.70 square feet and is located in the western
portion of the site in Outlot A. 1
The City Code requires that development within 200 feet of a Class A wetland shall receive a
wetland alteration permit. No alteration is proposed as part of this plat request. The wetland has
I
Bluff Creek traversing through its center. Vegetation predominant in the area is reed canary
grass. As stated earlier, there is to be no alteration of the proposed wetland. Building pad
locations exceed the required 75 foot setback and are in fact, located in some cases, in excess 1
of 160 feet. There will be adequate area for sheet flow from the proposed housing pads to
eliminate impurities reaching the wetland area.

PLANNING COMMISSION UPDATE
I The Planning Commission reviewed this proposal on June 3, 1992. Some of the issues that were
raised at the meeting were in connection with the rear yard setback variance. The commission
I felt there was no justification for granting the variance and that the applicant should adjust the
property lines to eliminate the variance.
I A second issue was in regard to the horseshoe driveway for the existing "Chaska Brick"
residence. Presently, the horseshoe driveway accesses onto Audubon Road. Staff had
recommended this driveway be eliminated for traffic safety reasons, and Lots 7 and 8, Block 2,
I share a driveway off of the northerly loop street (Road E). This is an effort to reduce the amount
of access points accessing on Audubon Road. The Planning Commission felt that it may be
appropriate for the character of the property to have a driveway of some kind going out to
I . Audubon Road if it was acceptable from a safety standpoint and agreeable with Engineering
Department. Engineering staff has prepared drawings showing the acceleration and deceleration
lanes on Audubon Road. The driveway encroaches onto the proposed lanes and is not desirable
1 from Engineering's view point as it could cause a safety issue (See attachment #9).
In general, the Planning Commission was satisfied with the proposal, and recommends approval
I of the application with minor changes to the conditions of the Preliminary Plat.
RECOMMENDATION
I Staff recommends the Planning Commission adopt the following motions:
1 Wetland Alteration Permit
"The City Council approves Wetland Alteration Permit #92 -6 with the following conditions:
I 1. All wetland areas will be rotected during construction by Type III erosion control. The
1 P g Y YP e
erosion control shall be maintained in good condition until the disturbed areas are
stabilized.
I 2. The wetland area remain undisturbed.
3. The applicant shall receive a permit from the watershed district.
1 4. The applicant shall meet all conditions of the Subdivision #92 -5 and Rezoning #92 -3."

RE: BLUFF CREEK ESTATES, PRELIMINARY PLAT, CASE 92 -5 SUB, 92 -3
I REZ, AND 92 -6 WAP, BLUFF CREEK, CITY OF CHANHASSEN, CARVER •
COUNTY
I Dear Ms. Al -Jaff:
We have reviewed the site plans dated 5/4/92 (received May 7, 1992)
for the above - referenced project (N 1/2, NE 1/4, S.22, T.116N --
' R.23W) and have the following comments to offer:
1. Protected watercourse Bluff Creek is on the proposed site.
I Any activity below the ordinary high water (OHW) elevation,
which alters the course, current or cross - section of protected
waters or wetlands, is under the jurisdiction of the DNR and
may require a DNR protected waters permit.
U The OHW for Bluff Creek is the top of the bank. Please
contact this office if there is any question about whether
I proposed activities will be within Bluff Creek and we can make
arrangements to determine the OHW .
I 2. There is a large wetland fringe on Bluff Creek that is not
under DNR jurisdiction. The U.S Corps of Engineers should be
consulted regarding pertinent federal regulation for
activities in wetlands. In addition, impacts to these
I wetlands should be evaluated by the responsible governmental
units (the city and Riley - Purgatory -Bluff Creek Watershed
- District) in accordance with the provisions of The Wetlands
I Conservation Act of 1991.
3. Portions of the site are within the Bluff Creek shoreland
I district and the floodplain district. The project must be
consistent with the city's shoreland management regulations
and the floodplain regulations of the city and watershed
district. No DNR concerns with shoreland management or
I floodplain regulations were noted.
4. It appears that most of the stormwater is routed through
I settling basins, which is good. We would object to having the
stormwater routed directly to the creek or wetland.

5. There should be some type of easement, covenant or deed
restriction for the properties adjacent to the wetland areas.
This would help to ensure that property owners are aware that
the wetlands cannot be altered without appropriate approvals
or permits.
6. Appropriate erosion control measures should be taken during '
the construction period. The Minnesota Construction Site
Erosion and Sediment Control Planning Handbook (Board of
Water & Soil Resources and Association of Metropolitan Soil
and Water Conservation Districts) guidelines, or their
equivalent, should be followed.
7. If construction involves dewatering in excess of 10,000 '
gallons per day or 1 million gallons per year, a DNR
appropriations permit is required. You are advised that it
typically takes approximately 60 days to process the permit
application.
Thank you for the opportunity to comment. Please contact me at 772-

BACKGROUND '
•
This item was initially reviewed by the Park and Recreation
Commission on January 28, 1992. The information presented to the
Commission that evening and the corresponding minutes are attached.
This item was scheduled for additional review in February, but was
subsequently removed from the agenda. Since the Commission's
initial review of the proposal, the city has finalized the
acquisition of the 8.6 acre park site in the Stone Creek
development.
PARK
The City has the ability to acquire approximately 3 acres of park '
property (comparable to Greenwood Shores Park), or a portion
thereof, if we wish to. If acquisition of developable parkland was
pursued, however, the city would forfeit all or a portion of the
$39,000 in park fees which would be generated from this
development. I do not advocate the pursuit of park property in
this case for three main reasons:
1. The portion of this site on which homes would be constructed
lies wholly within the park service area of Power Hill Park,
and partially within the service area of Sunset Ridge Park.
Me new park in Stone Creek, once connected to Bluff Creek
estates via trails, will also be utilized to some extent. The
barriers to travel mentioned earlier impact these service
areas to a degree; but future trails, and additional
residential street construction will lessen their effects.
However, increasing vehicular traffic along Audubon Road will
off -set these improvements somewhat. '
2. Outlot A, as identified in the preliminary plat, is comprised
of 19.7 acres of property wholly within the flood plain of
Bluff Creek. Via a trail connection being provided by the
applicant, this area will meet a variety of desired open space
needs. '
3. The number of individual park sites operated by the city is
relatively high. Acquisition of an additional small park site
would perpetuate this phenomenon. '
PARR PROPERTY RECOMMENDATION
It is recommended that the Park and Recreation Commission recommend 1
the City Council require full park fees be paid as a condition of
approval of Bluff Creek Estates. Fees to be paid at the time of
building permit approval in the amount of the park fee in force at
the time of building permit application.

Bluff Creek Estates
May 19, 1992
Page 3
1 TRAIL
As mentioned, the preliminary plat identifies the western 19.7
' acres of the site as an outlot. This entire area is below the 100
year flood elevation and will contain a portion of the Bluff Creek
Corridor turf trail identified in the city's Comprehensive Plan.
This outlot extends to the east in a bottle -neck fashion, abutting
I proposed Road E, allowing for pedestrian access from the
residential street. The second trail associated with this site is
the proposed Audubon Road off - street alignment. Through
11 consultation with the city's engineering department, it has been
determined that no additional right -of -way is necessary if this
trail were to be constructed west of Audubon Road.
TRAIL RECOMMENDATION
It is recommended that the Park and Recreation Commission recommend
' that the City Council acquire ownership of Outlot A, allowing for
continuation of the Bluff Creek preservation corridor, and require
the installation of an 8 ft. bituminous trail surface from proposed
Road E to the rear of Lot 1, Block 1 and Lot 1, Block 3 as a
condition of approval of this plat. In consideration for this, it
is recommended that the city give full trail fee credit to the
applicant.

' SUBJ: Pending Subdivision Reviews
a. Bluff Creek Site
b. Hans Hagen Homes
1 This item was prepared to afford the Commission the opportunity to
look ahead at above mentioned potential developing sites in
Chanhassen. Both sites are proposed single- family developments and
are adjacent to or in close proximity to the recently reviewed
Chanhassen Business Center (see attachments #1, #2, and #3). The
impact of these proposed subdivisions in the areas of fees, parks,
' trails, trail corridors, open space and natural resources is
significant. Portions of the borders of both sites include areas
designated for trails. The Bluff Creek site contains property
' through which the Bluff Creek Corridor Trail will travel (see
attachment #4). Both sites are isolated from existing neighborhood
parks, however, the Bluff Creek parcel is partially within the
service area of Power Hill Park (see attachment #5).
' To date, only preliminary discussions have been held with the
owners and developers of these properties. Upon receiving a
preliminary application of subdivision, these items will be brought
' - back to the Commission for detailed analysis.

Park and Rec Commis: Meeting

ADMINISTRATIVE PRESENTATIONS:
IF
A. LAKE ANN PARK UTILITIES AND PICNIC /RECREATION SHELTER UPDATE.
Hoffman: Item a is to discuss briefly the utilities which went in at Lak
Ann Park. As you've driven by you've seen the big...trenches. The wire is
down to the beach location. They've got the 3 1/2 inch forcemain sewer ji
line over to a lift station in Greenwood Shores. B & D will come in and
restoration work and install the lift pumps and all those types of things
in the spring. Picnic /recreation shelter was taken back. Approval for
readvertising for bids for the City Council at their first meeting in '
January. Those advertisement for bids are going out this coming week in
the Villager and the construction bulletin. We open bids the third week in
February and hold my breath for a reasonable bid. The target zone right II
- now is that it needs to be below 240 in order for it to be approved by thdl
City Council. Last bids came in at $280,000.00.
Lash: But there's been alterations right? '
Horfrr &n: Correct. There were some minor alterations in an attempt to
b: costs down and hopefully this bidding climate now in the spring"
- :ter than it was last fall. Our economy is somewhat weak.
,e have a better bidding climate as well as people will be hungry
. If all things work out right. The schedule is there.
II
_ this would put a completion date right at the end of the
_e&Eon so we would have a nice beautiful, brand new building to close
c,:�.. the beach.
Lash: Maybe we need that big Labor Day, our first annual Labor Day I
celebration. Have Oktoberfest there.
B. PENDING SUBDIVISION REVIEWS: 1
Hoffman: Iter 10(b) is of interest, particular interest to the Commission
The filet, these are just information on pending subdivision reviews. '
These developers have been in. Talked to the Planning staff. Discussed
park issues. Trail issues. Easement issues with staff. Preliminarily
bringing them to you this evening for some discussion. Especially on the II
Bluff Creek site. These folks are real tentative. If the Commission is
going to want some park property, they want to know that so they can try to
incorporate that into their plan. Or if we want to take fees, that sort oll
thing. This really brings about, the entire next area of development.
This quadrant of the city was developed with the business park, Lake Susan
Park and then Lake Susan Hills West and Chanhassen Hills back on the map.
So that section has been developed. The next one which is,coming in is il
this entire ring... Essentially with agricultural fields or a large lot
residential and now... Chan Business Park was recently reviewed by the
Commission and that's coming around. The Bluff Creek site which we're
II
discussing this evening is this particular location. As you'll notice,
I don't know if the topo shows through on the map...it goes from very high
ground or this end, breaks about here and drops essentially right on top o
creek so it's a very odd site in that there is a lot of grading... That's
a concern of the developers...very little flat, high ground... Hans Hagen
Homes is the other one which is in for development. Again its single
II
II
Park and Rec Commis Meeting
January 28, 1992 - P age 38
family residential in this entire area. Initial discussions have centered
around flag lot as being a 7 acre park. It's very wooded down in this
section with a hill coming up... It does have some flat area right in this
' area... The other issue which needs to be addressed here is the trail
corridor coming down to this other segment. You have a section of it right
on the Bluff Creek site. We also want to obtain a connection from the Hans
Hagen site down to this trail and by- pass...get onto the Bluff Creek trail.
And the Comprehensive Trail plan does identify trail segments around this
entire piece so as these subdivisions touch the adjoining roads, we need to
take a look at securing the necessary easements as well there to provide
for those trails in the future. Hans Hagen was in with the Planning
Director. Their initial development plan, site plan. It's not going to
fly so they're back out for redeveloping their site plan. Bluff Creek, I'd
II like to take a further look at. To get your directions. Take a look at
your site map se you know where this is. The service area of Power Hill
Park does touch this site and a potential service area of the Hans Hagen
park would service this site. It's approximately 75 homes which is a
' difficult number. It's on the fringe of if you had a 125 homes, I feel the
Commission would feel a great need to incorporate some type of active park
site within that development. If it was 50 homes, we could certainly get
' by without it. 75 homes on a site which is very small, we can take about 3
acres. We have the obligation or the right to take about 3 acres of park
property. If we take 3 acres of park property here and create another
' small neighborhood park that we need to go out and maintain, and is it in
the best interest of the city to forego the park fee in this instance? As
you can see, this is about the break line of the bluff back up in here.
They just have to just continue the lots down in this area, in this
' rema_`ninc...E1,.rf Creek when they encompass that trail. That portion of
the trail and this section may indeed just be a huge outlot. The thing
that we continually need to protect is naturally a developer comes in and
they want to give you that outlot for park credit. The City ordinance says
that that's nct acceptable. Anything below the high water mark just is
not, cannot be calculated into park credits so you have a battle right off
the bat. If the Commission felt that we needed to take 3 acres of this
' high, ground, yo,.' can bet they're going to be before you pleading their case
on -r they would not like to see that happen. So again so I can get back
to the people working on this particular site, this evening I'd like to at
least get your feelings on what you think on parkland and access to
recreational facilities as it deals with the Bluff Creek site.
' Pemrick: What are they coming as the lot sizes here with 75 homes?
Hoffman: Can you pick it up on there?
Pemrick: I can't. I have a hard time reading these things.
Lash: It looks like they're 16,000.
' Andrews: About a third of an acre roughly.
' Hoffman: Yeah, 15 to 20. Most of them are in right around 15.
Lash: How many sites are there in the Hagen?
Park and Rec Commis Meeting , ' ' II
January 26, 1992 - Pages 39
Hoffman: Hans Hagen?
li
Lash: Yes. . •
Hoffman: 140. 157. Something of that nature. 150 for a ballpark numbe
Pemrick: Is that the same again? About a third of an acre.
II
Hoffman: In that site, no. They'd be about 6 doubles so about 6 acres.
That flag lot up there is just over 7 and in our initial conversations, i
would be basically a wash. They would be willing to give 7 acres for the
dedication.
Pemrick: I'm just thinking with that small lot, the 75 homes, I think thl
should have a park.
Lash: I do too.
II
Fenric:k: I don't think they should borrow from someone else because that's
really cramped.
La.Sh: Hc•w fair would it be? See I would not consider Power Hill to be II
acceptable beca,:se if this area is now going to be developed with homes and
businesses, Audubon is going to be a substantial enough road that I
II
wouldn't be comfortable with children having to cross Audubon. In an
unccntrrlled intersection there wouldn't be any intersection there. To get
to Power Hill. How far would it be from Bluff Creek if we had a sizeable'
Park in the Hagen site, how far would it be if there was a fairly easily
accessible trail between the two neighborhoods.
Horfrr&r : It would be within the half mile but it would certainly not be
after school walk every day to go over to the neighborhood park. It woul
be MCre of a special trip type of operation. Obviously there is going to
be considerable open space on this site simply because of the outlot that
going to be there so the developer has to, site constrictions says they
have to put all their houses on this end and leave this end open. So there
are but they have to buy the entire piece. So then we want to take 3 acr
from them. We need to identify and obviously if we want an open field it
got to be up on the high portion.
Andrews: All the prime land.
II
Hoffman: Yep. As all developers say, it's the prime land. It's going to
sell the best for them and you're going to take 3 acres. Essentially we'll
going to lose about x30,000.00 in park fees to buy that 3 acres or in
excess of that and we're going to need to identify a location where we'd
like to see that park and get back to them. Prior to redesigning their
site plan, they'd certainly want to come in before the Commission
• officially on February 28th to present their case in that regard and then II
it would take action from the Commission to proceed further.
Las! Could you point out the outlot again?

;anuary 28, 1992 - Page 40
11 Hoffman: The low lying area would all be in this point. That's
essentially the high water mark down would just be grass, open area down to
the Bluff Creek watershed. Again each neighborhood and city has a focal
' point. Whether it be a neighborhood park or a school or grassy open area
or big woods. Kids from this neighborhood are going to go down in that
• outlot and play and icf that fills the recreational requirements of that
neighborhood, and we benefit by taking $40,000.00 in park fees, that's
' great. If we feel it not, then we need to take a look at acquiring
additional .land.
Schroers: What I would like to see here is a more clear overview of this
proposed site and how it fits into the area around. I mean it's difficult
when you're looking at these itty bitty squares and things here to get a
' real good feeling of what's around. logistically it's kind of hard. I'd
like to know right exactly where Sunset Ridge Park and Power Hill Park and
sturf fit in pvop;rtion to this and it seems to me this might be an
opportunity to capitalize on generating some fees. Some funds that we
'
could put to use in other places. It may be a good opportunity to acquire
some money rather than property but I just don't have a good feeling when I
lock at this as to how it all fits in.
^ ^t to make one comment and that is, if 75 homes go in there
pair:, can guarantee you there will be somebody up here saying we
don't have anyplace for our kids to go and play. You know you're going to
' her that. But I don't think we need 3 acres either. I guess I feel we
c:oL'_ : meet the needs here with maybe something closer to a half or even an
acre which is a totiot and a hoop to shoot baskets or something like that.
Lass.: At least you have an open area. Throw in some playground equipment.
Ths, car go there and fly a kite. They can shoot some hoops or they can
'
have just a quicky baseball. When you have just a third acre lot, you
car't play anything on a third acre lot and even with the high water line
back here, that's somebody else's property. Even if half of them think
it': fin for the kids to go back there and play and the other half don't
' have kids or whatever and they don't want the kids there, it's marshy half
the year and the grass gets real tall. They can't go back there and play a
garr,e of tall or anything. So if we could pick a site that is high enough
' so we could develop it and it would fill our needs but it would be more one
of the undesireable lots. Say one that backs up to Audubon. Maybe that's
one that wouldn't be as desireable for them to develop or it would be one
' of the last ones for them to develop anyway. Take one that's a peculiar
shape •like say 1 and 3 even. If you put two of them together, you'd have
almost a square but if you look at them both individually, they're both
kind of pie shaped. That's kind of an odd shape for a lot to try and build
' a house on and it hacks up to Audubon. So maybe those are -two
disadvantages that we could use in our favor. Although they're at the end
of a cul -de -sac which is nice for people, it'd really be nice for a park.
' Schroers: It's possible that if you go, if you do something like you're
suggesting that you could cash out on a deal. You could use 1 acre of
' property. Collect fees for the other 2 acres and use those fees to
purchase the equipment to put on that property and have a wash.
Park and r.ec Commis Meeting
January 28, 1992 - Page 41
Koubsky: Todd, do we know what Chan Business Center is doing? This abut
there? I mean like your park location would abut the Chan Business Cente .
We have trails that were proposed there.
Hoffman: Chan Business Park has the large outlot as well which runs north,
and south over the creek area. Right where the trail will go through.
It's essentially a commercial /industrial center with there's a 100 foot
buffer zone on the south side of their property which is on the north sid
of the Bluff Creek site. And there's a potential trail to run east and
west on that upper site.
Koubsky: 8o that might be a good place to abut a park would be on a 100 II
foot easement.
Hoffman: Correct. '
Lash: Arc' that also would make it more undesireabie for someone abutting
the business. '
Schroers: This is going to come up in front of us again I presume.
Hoffman: Correct. i
Schroers: Can we ask that next time, is it possible to fit this into a
better c.,erlay of the area so we can see how things are laid out a little 11
bit better than this?
Ho - Ffman: Okay. I simply brought this to you just as a pending subdivisill
just so ,ou can Pet some idea. The site plan does show it hopefully in
sore context to Hans Hagen and Chan Business Center, the Bluff Creek site
and there it also shows Power Hill Park and Outlot G. Just some words on, I
recently we've been looking at subdivisions and we're land grabbing and
that's Vacant land is the first and irreplaceable to a park. The
money can come later but if we forego park fees on this site, we forego
park fees on Hans Hagen, there's going to be a year down the line where 11
we're nct goinn to have a capital improvement program simply because we
have no revenues coming in. ...or we take a minimal amount of the
• revenues, we're gcing to be left holding the bag. '
Schroers: Well that's exactly what I was saying with this density. This
looks like a reasonable opportunity to collect some dedication fees and
still be able to provide something adequate for the community. Not
something that's only adequate but something that would be acceptable.
Hoffman: It's a real tricky balance. We don't want to end up with anothe'
Pheasant Hill where we spend 5170,000.00 to try and meet their needs. But
park service areas were set up for a reason and that's to accomplish what
is a comprehensive park plan and what is identified as meeting the needs. II
So again, I have mixed direction to give to the developer. I'll take that
to those folks and we'll bring it before the Commission again in February.
Lash: You know another option that they may be more inclined to accept '
would be, a couple of the lots that are right by the high water level and
then we'd end up with a.
Park and Rec Comrniss . ,Meeting
January 28, 1992 - Page 42
Koubsky: A hill.
Lash: Well.
Hoffman: If you want a play area, we need to take something on the
easterly third or easterly half.
1 Koubsky: I guess I think each area needs some sort of playground. It may
be an acre. I don't think we need 3 acres or whatever but I think they're
' far enough away from existing parkland. They've got roads and a railroad
track there. They each need some sort of area.
Lash: I think we need to look at each one individually. At the physical
' characteristics and this one has several I think. You're looking at
Audubon. You look at the railroad track. You look at the fact that
there's a business center abutting it. It's kind of secluded as it is
right row.
Koubsky: Pecause we'll also have Sunset Ridge Court there and Timberwood.
We'll have the school going north of it but they have bigger lots but they
don't ha,'e playground facilities.
Schroers: Do you have what you need on item (b) now Todd?
1 Lash: what is the minimum that, I know that there was sort of some kind of
a policy estaklished at one time about the minimum that we would take for a
neighbcrhood park. Just so staff didn't have to go out and maintain 50,000
half acre parks all over town.
Schroers: It was 5 acres originally.
1 Lash: Now we're talking about 1 acre.
1 Hoffman: One acre is half of the size of Carver Beach playground.
Schroers: You can't really do much more than a totlot. What else could
you do besides a totlot. If you put in a totlot, what else do you put in
11. there?
Pemrick: volleyball.
Koubsky: Some open area.
' Schroers: Yeah, we could put in volleyball. Picnic table
Hoffman: You're not gaining that much more open area than a backyard in
' this area. That's the word of caution. We don't want to create, you know
40 more subdivisions of this nature come into the city. do we want 40 one
acre parks within our city?
Schroers: No, I think we're better off looking at trail easements and
connect them to a park that's more substantial that's going to serve the
area rather than give each little nook it's cranny. Definitely.

Park and Pec Commis Meeting • • II

Hoffman: It's an issue which needs to be addressed because of the II
accessibility and that type of thing. Bluff Creek corridor would provide
access, safe access to the Hans Hagen site. We could negotiate with that"
site and acquire land closer to this site. Closer to this end of the
corridor. Open space and that trail, it's not a traditional play structure
which we identify with but it does provide recreational activity that pie
of it. r
Schroers: Well we did want some diversity in our parks. We don't want
them all to be the same thing. I guess there's nothing wrong with just I
having a green space and an open area and it doesn't have to be overly
developed. It can just be maybe maintained to a point where - people can
create their own type of fun there. I mean keep the noxious weeds down.
some mowing and that sort of thing and just give them space so they can d
whatever they wart to do.
Pemrick: How about requiring larger lot sizes? 1
Hoffman: Sack to the Planning Commission.
Pernr i c k: What do they say?
II
Hoffmar,: €)'11 go through that and they have the ordinances set...
Erickson: Todd, how far did you say that this Bluff Creek is from the Ha IL
Hagen? That proposed 7 acre park.
f - The walk from the Bluff Creek site would be just over a quarter,
- It's within the half mile service area. You could go north through
site underneath the railroad tracks. Take an immediate left ther
a o ,t half a block and you're at the Hans Hagen site. Their
ori_":;_ proposal put an on street trail through a portion and then you
cross the ra.iine and you're up into the park area.
Erickson: You say it'd be about a quarter mile?
Hoffman: Yes, just over a quarter mile.
II
Schroers: I don't think that's an unreasonable distance to get to the
part I mean at some point in time you have to take responsibility for
you �_lf. If you feel that your children are too small to go that quarte
of a mile by themselves but you think they ought to go there, then you've
got to take them there. I mean you can't dump a park on everybody's
doorstep where everybody can look out their window.
II
Erickson: Plus it's not really a quarter mile across Audubon or something
like that. 1
Hoffman: It may not happen. The Bluff Creek site may develop fully in 4
years and Hans Hagen may be 10 years down the line so we need to deal wit
that issue. It's something when you're in a developing city, you just
can't control.

Lash: If that's the route we decide to take, let's make sure we have some
kind of an access site that's not going between two lots through to the
Hans Hagen area to get to the park for these other people.
Schroers: Our service area was set up to be a half mile wasn't it?
Hoffman: Yep. This will be within the half mile as Power Hill will be on
the fringe district. I'll lay that out for you.
Schroers: I think that's something we can work with.
Berg: Plus if you build close enough on that end, on the other side, the
other people from Hans Hagen could use the school if it's built too.
. They'd have access to the facilities there, if it was built there.
Hoffman: Okay. Anything else?
11 Lash: Do we need a motion on this thing?
Hoffman: No.
Schroer_: Okay, we beat item (b) to death. Quite an indoctrination for
these g::ys .
' Berg: This is normal right?
' Schroers: No. Sometimes we bleed a little more.
C. STATUS REPORT, SKATING RINKS.
Ruegemer: Just to give you a real brief, tell you what's happening with
the skatinc rinks in Chanhassen. We did have a mid - winter warm spell right
after the first of the year where it did get really nice out. Typically
unse.asor,atle for January but it did do the skating rinks very much good.
Basicall) what it did do is we had to close down the rinks because they
were getting very slushy and very dangerous to skate on. Virtually it did
' create a...almost we had to start over again. So what we really did hope
for was to get some colder weather in, as we did and park maintenance crews
did shave and get the ice back to where it was functional again. We opened
up back again January 25th and we have been open since that time.
Hopefully with weather cooperating that we can, this week is going to be
warm again the way it sounds. Up to 40. 36 tomorrow and 40 by the end of
the week so hopefully we can squeeze through this week and get to where our
target date of the 16th of February, weather permitting.
Lash: How do you set that target date?
Ruegemer: It's just kind of an approximation.
Lash: It'd be nice if you were going to have an approximation, to have it
after energy break.
Ruegemer: I think that's the middle of February too.

FROM: Dave Hempel, Sr. Engineering Technician /*
1 DATE: May 28, 1992
1 SUBJ: Review of Preliminary Plat for Bluff Creek Estates- Keyland Homes
LUR File No. 92 -10
Upon review of the preliminary plat, grading, drainage and utility plans prepared by James
R. Hill, Inc. dated May 4, 1992, I offer the following comments and recommendations.
1
Grading and Drainage
The overall development is proposed to be constructed in two phases with the initial phase
proposed along the easterly portion of the site adjacent Audubon Road. Ultimately, the
1 entire site will be regraded along with construction of two retention ponds along the
westerly edge of the property. Since the retention ponds are located in the far westerly
portion of the site (Phase II), the initial phase should provide for an interim or temporary
retention ponding to address water quality issues and fulfill the City's storm water retention
ordinance. The plans do not reflect any interim ponding or sediment basins and it is
assumed that the applicant will not be constructing the entire storm sewer at this time.
' Therefore, it will be necessary for the applicant to provide interim ponding with Phase I of
this development.
The first phase of construction proposes grading the rear lots adjacent to Audubon Road
to drain southerly along Audubon Road to Bluff Creek. Audubon Road currently exists as
a rural type roadway with a ditch section. Any increase in the amount of runoff will create
additional turbulence and potential erosion problems downstream. It is recommended that
the applicant's engineer redesign and raise the lot grades to minimize the amount of runoff
towards Audubon Road. Eventually, Audubon Road will be upgraded to urban street
standards with concrete curb and gutters similar to just north of the site adjacent to Lake
Susan Hills West 3rd Addition. It would seem prudent to grade the loth adjacent to
1

•
Sharmin Al -Jaff 1
May 28, 1992
Page 2
Audubon Road to be conducive with future urban design standards, i.e. eliminate ditch
section, build rear yards up to drain out to interior street (Road "E ") where practical.
1
Street grades are not shown on the plans based on contours; however, they appear to be I
acceptable except along Lots 25 and 26, Block 2. The street grades in front of these lots
appear to exceed the City's ordinance of 7.0% maximum grade. Therefore, a variance may
be required unless the developer's engineer redesigns the street grade to fall within the
City's guidelines of 0.50% to 7.0% grade. Staff believes this can be achieved. The proposed
house pads, in this same area, are approximately six feet above the street grade which
equates to approximately 13% to 15% driveway grade which is extremely steep. Typically, I
the City requires that the driveway grades not to exceed 10 %. It is recommended that the
developer's engineer redesign and lower these lots so the driveway grades do not exceed
10 %. 1
Storm runoff generated from streets and lawns is proposed to be conveyed overland via
surface drainage to a series of storm sewers which will convey runoff into two retention I
ponds. The applicant's engineer should submit design calculations for the storm sewer and
retention ponds. Storm sewers should be designed for a 10 -year storm event and retention
ponds shall retain the difference between the predeveloped and developed runoff rate for
a 100 -year single storm event. The outlet of the pond shall be designed to restrict the
discharge to the predeveloped runoff rate. Ponds shall also be constructed to "NURP"
standards to improve water quality. 1
As part of Phase I construction, no storm sewer improvements are proposed to be
constructed. Road E becomes a very long street with no storm sewers. It is recommended 1
that the applicant's engineer provide an interim retention or sediment pond and storm sewer
plan to deal with street and lawn runoff.
Staff recommends the applicant supply earthwork calculations to the Qty to determine if
the site earthwork balances or if the site requires imported material or to export. Staff
requests this information to determine if appropriate traffic signage will be required or if
additional financial security requirements are necessary.
. 1
Utilities
Municipal sanitary sewer and water sewer currently is not available to this site. However, 1
the City has authorized preparation of plans and specifications to extend trunk sanitary
sewer and water facilities down along the west side of Audubon Road which will service
Phase I of this site. Phase II of the development will be serviced via a gravity sewer line
from a proposed trunk sanitary sewer which the City will be extending north from Lyman
1
Sharmin Al -Jaff
May 28, 1992
Page 3
Boulevard adjacent to Bluff Creek. The applicant will have to cross over Bluff Creek in the
future to extend sewer service to Phase II. Depending on the City's trunk improvement
project scope and timeframe, the utility lines may or may not be operational by October,
1992. The City's project will include special assessment for both trunk and lateral sanitary
sewer and watermain service to this development. The preliminary plat is dedicating
sufficient right -of -way and utility easement for installation of the City's trunk sewer and
water lines.
' The utility layout proposed on the utility plan sheet is fairly well laid out. Hydrant spacing
may be of concern to the Fire Marshal and require additional hydrants. The Fire Marshal's
rule of thumb for hydrant spacing is typically 300 feet apart. There are some areas that
exceed this limitation and will need to be modified. Watermain sizing is not given on the
preliminary plans and should be evaluated by the applicant's engineer. Detailed calculations
' demonstrating sufficient fire flow during peak demands should be supplied to the City
Engineer for review. Final construction plans may be prepared in conjunction with the final
platting process. Utility and street construction plans and specifications shall be prepared
using the City's most recent edition of the City Standard Specifications and Detail Plates.
1 Streets
The preliminary plat proposes a loop street with two access points on Audubon Road. The
' access points appear to be located to accommodate future extension of the street east of
Audubon Road. It appears the site distance of the southerly access is acceptable based on
MnDOT's standards. The right -of -way is proposed at 60 feet which is the City's urban
standard. It is assumed the streets will be constructed to the City's standard 31 -foot wide
back -to -back street section. Street grades are not provided on the plans, however, based on
contours, it appears the majority of the street grades will be under the 7% maximum grade
' per City ordinance except in the area in front of Lots 25 and 26, Block 2. It is
recommended the applicant's engineer review the grades to see if they can be reduced to
meet the City's ordinance. Staff feels confident that the streets grades could be negotiated
to fall within the City's guidelines (0.50% to 7.0 %).
According to the Eastern Carver County Transportation Study, Audubon Road is classified
as a Collector Class I street. This type of street requires a minimum right -of -way of 100
feet. Audubon Road currently exists with 66 feet of right -of -way, 33 feet on each side of
centerline. The preliminary plat proposes dedication of an additional 17 feet of right -of -way
to arrive at half the necessary right -of -way together with an additional 20-foot drainage and
utility easement to facilitate trunk sewer and water improvements the City has proposed
1 along Audubon Road.

Page 4 i
The site currently contains an existing "Chaska" house which driveway accesses onto
Audubon Road. It is recommended with Phase I construction the driveway access be
eliminated from Audubon Road and relocated to access the northerly loop street (Road E).
A driveway access easement would be required across Lot 7, Block 2. Staff feels this would
be a safety improvement by reducing the amount of access points along Audubon Road.
It should also be pointed out that Lot 9, Block 2 should also gain its driveway access off of
the interior street (Road E) and not Audubon Road ,
The southerly road access proposes an island barrier at Audubon Road. 'This island should
be removed. If the applicant is interested in having an entrance monument, we recommend
that it be placed along the adjacent lot's corner. A deceleration and acceleration lane
should also be constructed along Audubon Road in conjunction with this development.
Audubon Road is constructed to rural road standards with 24 -foot wide bituminous surface
foot gravel shoulders. North of Heron Drive, Audubon Road has been recently
_rutted into a 44 -foot wide urban section with concrete curb and gutter and a trail
:n along the east side. It is anticipated that in the near future, Audubon Road may be
upgraded to urban standards as development pressures warrant upgrading. The applicant
should be aware that this development may sustain some of the costs for the upgrading by
means of special assessments.
Erosion Control ,
Plans propose erosion control along the westerly, northerly and southeasterly property lines.
T commended that the proposed erosion control fence be the City's Type III along the
(Phase II construction) and Type I silt fence along the north and southeasterly
of the development (Phase I construction). Additional erosion control fence should
be installed on Lots 7, 14 and 15, Block 3 as check dams, as well as, Lots 8, 10 and 11,
Block 1. The side slopes along the rear of Lots 1 through 5, Block 3 are steep,
approximately 3:1. It is recommended that an erosion control blanket be used on slopes 3:1
or greater throughout the development and that all disturbed areas be seeded within two
weeks after grading unless MNDOT's planting season dictates otherwise. 1
Miscellaneous i
The preliminary plat proposes 15 -foot wide drainage and utility easements over the storm
sewer lines proposed along the interior lot lines of the development (outside street right -of-
way). It is recommended that the 15 -foot wide easement areas be increased to 20 feet wide
to insure adequate room for access and maintenance vehicles. The preliminary plat also
1

dedicates a drainage easement over Lots 7, 8, 10 and 11, Block 1 for a rear yard drainage
' swale. Staff recommends that the drainage easement also be extended to include Lots 12
and 13, Block 1.
•
Recommended Conditions •
1 1. All storm sewer drainage pipes should be designed for a 10 -year frequency storm
utilizing a rational method.
2. Storm drainage retention pond, detention areas and outlet piping shall be designed

Aanenson: Then on the boats on land, that would be included in total
number of boats?
Emmings: Well yeah. I was afraid, yeah.
Aanenson: Well canoe rack, we're assuming you can put 6 canoes in there.
I guess we can put it that way. Is that what you're assuming?
Emmings: Yeah, I'm assuming that the canoe rack is. Any boat that's not a
' powered boat. A sailboat's fine. A 12 foot fishing boat is fine. I think
we lived through that when we talked about canoe racks originally. Canoes
are fine but not boats with motors.
' Conrad: And you agreed with the power lifts?
Emmings: Yeah. And the rationale there is the lift is just one way to
' dock your boat and why get into it.
Ahrens: Is there a second?
1 Erhart: Yeah, I'll second it.
Emmings moved, Erhart seconded that the Planning Commission recommend that
the Pleasant Acres Non - Conforming Recreational Beachlot be allowed to have
tw: ocks, one 96' x 67' in length and the second one 96' x 12' in length,
with space for 10 motor boats to be docked, continued use of the boat
launch, parking, chemical toilet, motor vehicle access, and swimming beach.

Planning Commission . ing . I
June 3, 1992 - Page 20
II
Ahrens: Sharmin, I have a question about, on page 2 of your report where II
you talk about Williams Pipeline Company with their 75 foot easement. And
you state that, the third sentence down. Your questioning the design of
two lots, Lots 10 and 14, Block 2, that they're buildable. What about all'
the rest of these lots? Like I guess Lots 11 thru 13 also and 29 and 30.
Al -Jaff: Usually when we look at a parcel, we make sure that you can piaci'
an average home with dimensions of 40 x 60 feet. You can place a 40 x 60
feet on those parcels.
Ahrens: On these other ones? 1
Al -Jaff: Yes.
Krauss: If I can add too Commissioner. The easement is useable as rear II
yard area. The home just can't be in it or a deck can't be in it but
gardens, yards, possibly even play structures I suppose can be within that
area.
'
Emmings: How deep is the pipeline?
Al -Jaff: Normally it's 3 feet. II
Krauss: The pipeline itself?
II Al -Jaff: Yes.
E Is that all?
II
4, When we spoke to the pipeline company, they said becuase this
aj� been farmed, they might have lost some soil but normally it is a II
deptr; of 3 feet.
Ahrens: But there's no problem with Lots 11 or 13? They could fit a
40 x 60?
II
Al -Jaff: We don't foresee problems with it. Unless they decide to build
extremely large homes which then we would recommend that they find ,
different sites.
•
Ahrens: I hope the City makes sure that there are signs put up in their II
backyards warning them not to plant trees back there.
Al -Jaff: Williams Pipeline usually sends their staff to meet with people
that live along the easement to educate them about problems that might taki
place if they should dig in that easement.
Ahrens: This is a public hearing. Is the applicant here?
II
Hill: Madam Chair, if I may. Jim Hill. Consultants for Keyland.
Ahrens: Sure, would you like to step up to the microphone please. 1
II
Planning Commission ing
June 3 1992 - Page
Jim Hill: Madam Chair, Jim Hill. Consultant for the applicant and the
applicant here is represented by Gary Horkey who's a principle of Keyland
Homes and Dick Schuller who is their sales and marketing director who will
' speak to the two lots that staff had concern about. Show you how their
homes can fit on those lots. 10 and 14. And then Rod Grams, the fee owner
who'd like to speak to you about the homestead driveway. If we may.
Dick Schuller: We had an opportunity to meet with staff here a few weeks
ago. She gave us a chance to look at this and suggested that we come up
with a couple, some plans that would fit on the lot. What we did is we had
the engineering company... And the line that you see across the front
there is the setback in front of the house and your 10 foot setbacks on the
side. The line in the back is a 10 foot setback along the pipeline
easement. Now an FHA loan you'd need to be 10 feet away from that easement
because all these homes are, in the range where they're really not going to
be getting that basic financing so conventional financing you can bring
your house all the way up to the dotted line. So we're within 10 feet away
from that closest point. 10 feet away from the easement line.
Ahrens: What about a deck on that?
' Dick Schuller: The deck would be on the west side but you're also 10 feet
away so you're 10 feet plus whatever this space is which is a good another
10 -15 feet on that side so you could put a real large deck there. This is
the house that one of our nicer homes that we'd be building. This is the
plan that. This would be the sketch if we got it platted out on Lot 14.
So it would be real easy for us to be able to build that house on that lot.
We don't see that as a problem at all.
Ahrens: Why does the City see that as a problem?
Dick Schuller: It's really difficult to see sometimes on a small picture
so we've measured it out.
' Ahrens: Sharmin?
Al -Jaff: We didn't think that you could fit a house easily on it. It
would be a tight squeeze.
Ahrens: What do you think of what he's saying here?
' Al -Jaff: What are the dimensions on it?
Dick Schuller: I had a little picture of it. This house here is 60 feet
wide and the deck on it is 34 feet. So it's not as deep of a house as 40
foot. That makes 60 of the different although when I think she originally
drew that up there was a concern about this 10 feet. Trying to stay 10
' feet away from that back easement line. That really isn't a requirement on
a conventional home so as long as we don't need to stay within, as long as
we go up to the easement line... But it's ,just less of a concern because
of that.
Krauss: It's our position that the developer has an obligation to
demonstrate that the lot's buildable in a reasonable manner. In this case
•
1
Planning Commission M '.rig

it appears that he's done so. I would ask you to let the condition stand II
and we would work on this a little bit more prior to City Council. You
konw I don't think they're doing that in this case but if you can squeeze a
certain building footprint onto a limited site and it doesn't mean that
has a great deal of flexibility. In this case it looks like there is ampl
room. And I guess keep in mind though that again that utility easement is
a great deal of open space. It is not, I mean it's the termination of a
buildable area but it's not the termination of useable space. But we'd
like to research that a little further.
Ahrens: Okay. '
Dick Schuller: That would be your one lot. This would be the footprint on
that one house. The other one is just, even easier for us to work on. Th
garage would be on, right there. We have movement left and right...street�
real well and then curves the way... Lots of space for decks out in the
back on the left side here. Or we could put the house around here
directly... ,
Ahrens: Would you like to address any of the other conditions set forth in
the staff report? '
Jim Hill: Madam Chair, the Keyland Homes accepts the report except for the
comment regarding the two lots which they've shown they can build on. And"
then Rod Grams would like to address the driveway on the homestead. The
other conditions are acceptable.
Ahrens: Thank you. 1
Jim Hill: I think he said he only has an hour to talk about that driveway.
Rod Grams: I've only got an hour. 1
Ahrens: You do?
Rod Grams: To keep you here. Thanks. I'm Rod Grams. I currently live on
the homestead and as most of you I don't know maybe are familiar with the
house, it's a Chaska brick farm home and it has a lot of historic value in II
the area and we've gone to great lengths in this project to try and
maintain that historic value of the house. Part of the Planning or in my
view is we've tried to put it on a larger area because of the uniqueness of
the house to blend in with the rest of the subdivision. But to take away
those two driveways would destroy the character I think of the way the
house sits now on the site because it wouldn't then match with the other
three homes along the same street. So what I'm proposing is that the II driveways be allowed to remain as they are because it is only for the one
house. And again it would stabilize or maintain the integrity of the site
as it is and the way the house is there now. So if you take those
driveways out and to push it off to the back I think would not maintain thell
integrity that is there now.
Ahrens: Do you see the driveways following the westerly lot line of 8 and II
7? Lots 8 and 7.

II Planning Commission . _ ing
June 3, 1992 - Page 23
Rod Grams: No. I would like to see them stay where they are. The
existing.
' Ahrens: Where is it now?
Rod Grams: They come rout to Audubon Road. And like I say, it's only for
I the one house so I mean you wouldn't get that much traffic from it but to
just leave the site as it is. Because to take the driveways out and to
change it, it would also change the whole apperance of the house and it
wouldn't.
Conrad: Why would it do that?
' Rod Grams: Because of the way it's setting there now. I think the way the
house is and the historical preservation efforts that have been made of all
the houses in that area. So I think to take the driveways out, I mean you
would change the whole appearance of what it is now. And we've gone to
great lengths to try and keep the house and to keep it and to blend into
this subdivision but it's unique and it should stay that way from the rest
' . of the subdivision.
Conrad: The driveway comes from Audubon and it goes straight up to the
front of the house?
Rod Grams: Correct. Between the house and the garage there on the side.
' Ahrens: It was a safety issue the city was concerned with right?
Al -Jaff: Correct.
Rod Grams: But it's there now.
Ahrens: But there aren't the other two roads. That Road E and Road D.
What's the minimum on a collector road?
Hempel: Access we consider 500 feet. I'd like to point out that Mr.
' Grams, is there in fact two accesses to that lot?
Rod Grams: Yes.
Hempel:. It's a horseshoe type driveway at this time so actually it's two
driveway entrances to that lot.
' Ahrens: Do you want to maintain the. horseshoe?
Rod Grams: It's been there all along, yes. I mean it's been there for, it
was build in 1900's so I mean.
Erhart: Yeah but you're tearing down the barn right?
Rod Grams: That's right.
Erhart: So I mean you aren't leaving it the same.
1

Planning Commission ' ing
June 3, 1992 - Page 24
Rod Grams: But we are trying to preserve the house the way it is. And thl
house is unique and to take it away and try to move the driveways out, then
you're trying to take a nice big old brick farmhouse and trying to conform
it to a lot where we're going to be building a newer house so it's not the ll
same. So we're just asking that the uniqueness that is there now, to stay
there the way it is.
Hempel: If I may add another point. We will be requiring deceleration an"
acceleration lanes into and from site and that may also impact the driveway
access to the existing house there.
•
Ahrens: I'm kind of confused about your vision of access to'Lots 7, 8 and
9. The City's. Sharmin, in your staff report you said it should be
pointed out that Lot 9 should also gain it's driveway access off the II interior street Road E. Are you expecting then that all three lots, 7, 8
' and 9 have access off of Road E?
Krauss: No, I don't think that's ever been proposed. We would typically II
put a condition in there just to make sure that that doesn't happen.
Erhart: 9 is the temporary one right? ,
Al -Jaff: Correct. That's when they will build a model home. It will be
sharing the existing driveway. That's where Road E goes then. 1
Dick Schuller: The reason we... This road right here, we're going to be
trying to be into the Parade of Homes this fall. Our concern is that this"
street may not be ready yet so we were hoping to be able to come
temporarily off of Audubon through Rod's driveway to get to our house.
When this street comes in, then this driveway's going to go here across
from Audubon... So that would just be temporarily that will be hooked
up...just for a month until, and we're not even sure that that will be thell
case. It depends upon how long or where we're at on the street.
Emmings: There's nothing that keeps you from putting in a paved driveway II
over that easement? That's fine is it?
Ahrens: Williams Pipeline allows a paved driveway over that? ,
Al -Jaff: Yes they do.
Jim Hill: Madam Chair if I may. Exhibits indicate that driveways... ,
Rod's talking about the homestead maintaining his own driveway along with
the Chaska brick home and not take away the individual access as there are"
some other Chaska homes, brick homes on Audubon and not as proposed by
staff to bring a driveway from here.
Rod Grams: We want it to remain. I mean if it does have historical value ll
and to have it retain that is important I think. I think the access there
is going to set it apart.
Ahrens: Okay. Anything else? Thank you. Would anyone else like to
address the Commission?

11 Erhart moved, Ledvina seconded to close the public hearing. All voted in
favor and the motion carried. The public hearing was closed.
Ledvina: One thing that I noticed as I was going through the information
here. I have some questions regarding the variance that was proposed for
that building. I'm wondering if staff could explain how the situation
meets the criteria for a variance because frankly I don't see specifically
why it's being proposed.
Krauss: Well, this explanation is not going to fall within the normal
legal context of a variance, which frankly was the reason that I wanted to
get a range of variances reviewed by the Planning Commission instead of the
Board of Adjustments. The Board of Adjustments is very good at taking a
variance in it's usual hardship context for a garage or for a deck or you
know, to make a lot buildable. What they're less adept at doing is taking
a proposal, a development proposal in total, you know that does this thing
work? Is this variance not so much a hardship but does it reflect the way
this property should reasonably be developed. And in this case we thought
it did. I mean theoretically you can bump property lines further out to
eliminate the variance. Conversely you can, or alternatively you can
require that the garage be torn down and moved. I mean we've done that. If
the garage is not in great shape, we've had that done in the past too. But
in this case there's a tree line back there. It lends itself to be the
appropriate place for the property line. Moving the property lines
significantly raised some problems with interior lots further in. So while
I can't tell you that it's a traditional hardship, it does fall within the
realm of things we've considered at times in the past. So I hope that,
that probably didn't put your mind at ease.
Ledvina: You know I look at the issue as far as the vegetation is
1 concerned and in the winter there isn't vegetation and you can see thru
tree lines. Our activities, our approvals at this point don't in the
future prevent those trees from dying or being taken out. I see the issue
with maybe contrasting building styles with an older shed or garage there
with newer style houses on I'm not so certain that that really works
together and I'm wondering if we should try to separate that as much as
possible by the ordinance. Is there another mechanism we can use besides a
� variance to allow this type of situation?
Krauss: Short of not catching it in the first place, no. There really
' isn't. I mean it does exist. Now again, there are alternatives and the
alternatives do include bumping the line or tearing it down. I'm looking
at the lot right behind it. Lot 5 is a 16,000 square foot lot and it's
possible that we could kick the lot line around a little bit to mitigate
that. I'm not sure we can eliminate it.
Ledvina: That would make that lot 14,500 roughly. 14,500 feet and that
would be less than if you took it off the whole map.
Krauss: No, it's 16,000 now.
Ledvina: Right. You could just do that along the southeast part of that
lot line.
1
Planning Commission _ ing
June 3, 1992 - Page 26
Krauss: We can sure look at trying to do that. "
Ledvina: Yeah, I would be against the condition for the variance. I just
don't believe that it meets the intent of, or the letter of the variance
and I think some alternatives should be investigated for that. Otherwise
really didn't have any other comment.
Emmings: I agree that we should do something other than a variance. Maybe"
we can be more flexible. I still think though...and I think if something
can be done to eliminate granting variances, it should be done. If they "
make that lot in back a little smaller, I'd rather have it that way. As
far as the driveways go, I guess I don't know how much distance there is
between the ends of the two ends of the U and particularly to the one to
the south would be more concern. There's only one person going to be usinil
that driveway so it isn't a lot of use but would you regard that as being
unsafe or too close?
Hempel: It sets kind of an example for the other 5 homes also that are "
• adjacent to Audubon Road which someday will be developed also. Their
access on a horseshoe driveway, granted it may be single use or whatever
but they do generate average 8 to 10 trips a It's an additional curb"
cut along the road and it may also impact an acceleration lane and so
forth.
Ahrens: What's the speed limit on that road? "
Right now it's 45. Actually it's probably a rural standard, sout
`rive it's probably 50 mph. There's a crest there however with
distance but eventually when the road is urbanized, similiar to
_ cone north of this development where it made the 4 lanes with curb
: er and so forth, use is intensified. More curb cuts out there.
Spec= limit may be reduced to 35 or 40 eventually.
Emmings: Does the County have anything to say about the number of accessell
onto that?
Hempel: No. This is not a county road. This is a city street.
Emmings: I guess what I'rn trying to get you to commit to is, do you think"
that it's a bad situation? A situation that should be avoided by us?
•
Hempel: We believe it is, yes. Or at least limit the driveway down to one"
access.
•
Emmings: That was my next question. If we take out the U and just give II
him a single drive in, would that make you feel any better?
Hempel: Every little bit would help. "
Krauss: If I could put into context. I don't remember the exact amount of
traffic that's being forecasted by the Eastern Carver County Study but I
thought it was somewhere in the neighborhood of 6,000 to 8,000 trips a day.
Emmings: For? "
II Planning Commission t Ong
June 3, 1992 - Page 2.
Krauss: When this area is fully developed. TH 101 right now is 10,000
trips a day so if that puts it, you can get a feel for that. So 50%-60% of
what you see on TH 101 today is going to be the ultimate traffic on Audubon
I Road.
Emmings: Another alternative might be to give them one driveway and put a
driveway easement across TH 7 and put that in our pocket in case it's ever
deemed to be a hazard?
Krauss: You can certainly use that as a fall back position but those
things tend to, if they're not utlitized at the outset, they typically
won't be. Also, as Dave points out, we do have similar situations with the
Chaska brick homes across the street. Now they're all sitting on 5 and 10
acre lots. In fact, the developer of Lake Susan Hills.
Hempel: Joe Miller Homes.
Krauss: Joe Miller Homes is talking to us about the possibility of
developing directly across the street from the north road. And that one is
a Chaska brick home. It's Willy Molnau's. And we've even seen a concept
for that one and as I recall, I thought it was going to access internally
off the new street.
Hempel: I've never seen it I guess.
Emmings: It's hard sitting up here to know whether this is dangerous or
not dangerous. I think as a general rule we should limit the number of
' accesses onto Audubon but I can see the point of wanting to maintain the
driveways since everything is oriented that way and my position on this
I guess would be that we go along with the, I'm going to have to go with
the City Engineer and say that the driveway is going to have to go out
through Lot 7, unless the applicant can convince the Engineer from now
until the City Council, that it's a safe thing to do. That's all I've got.
' Conrad: For our front yard width, what do we do? Especially on
cul -de -sacs. It has to have a 90 foot width at what kind of setback from
the road?
Al -Jaff: 50 feet setback.
' Conrad: And all these do meet that?
Al -Jaff: Correct.
Conrad: There are a lot of narrow lots here and fairly deep. The square
footage by the depth. But I guess I don't have a concern with that. I am
struggling, I don't think we should grant a variance that was for the out
building or the garage. But I am struggling with the curb cut for the
farmhouse. And I kept looking for another way to design this and I can't
do it in 5 minutes. I have a tendency to want to grant one curb cut for
the Lot 8. My concern is the, what is necessary for safety for Road E and
11 and I don't know that right now. Therefore, my tendency is to go along
with Steve's motion until the applicant can sell our engineer on the safety
and the engineer knows the acceleration and.deacceleration lanes. I think
1
Planning Commission eying
June 3, 1992 - Page 28
the farmhouse orients to the road. I guess that tends to sell me that it II
should have Audubon access but I'm going to go along with a motion similar
to Mr. Emmings to allow the applicant to. I'm concerned about safety and
need the applicant to be talking to the engineering department on that one
That's all.
Ahrens: Any discussion? 1
Erhart: Yeah I do have some. Maybe I'm tired and crabby but you know,
for 6 years I've been trying to get a plan on this Bluff Creek Greenway. II
Six years ago a development came in and put houses where I thought we
should have preserved a corridor. We were real lucky back then because
that development never got built. We all committed at that time to lay out
a plan so when south Chanhassen got developed, and properties which includil
Bluff Creek came in, that we'd have a plan. I walked out there this
afternoon and I had no foggy idea where, in walking around that property,
where the backs of those houses are going to be relative to this greenway 11
corridor. I'm looking at it and looking at the contours. I hope it
doesn't interfere with the vision that I share with a lot of people on this
greenway. But after this thing gets approved, the worlds not going to mov
it. I hope all of you, we got it on the action tonight and I don't
understand why the Park and Rec, who is spearheading this effort? Park an
Rec or is it us or who?
Krauss: Park and Rec has really taken this and hopefully is running with
it.
Erhart: Running with it? '
Krauss: There is no plan that exists. We have been taking land to get th
trail corridor in.
Erhart: I'm not talking about a trail corridor. We're talking about a
greenway here. '
Krauss: Well the greenway is there Tim.
Erhart: Maybe your idea of there and my idea of there might be two 1
different things.
Krauss: I think you've got a substantial amount. That's the half of the II
greenway that happens to be on this property. The other half is on the
other side. The creek channel itself is way up there.
Erhart: Okay, the line that you cross, does that include what's currently"
tilled also today down there?
Krauss: Yes. Part of that is. 1
Rod Grams: No, the line falls just about...
Erhart: So the tilling would be on it's under the high water mark or
above it? •
1
1
Planning Commission ing
June 3, 1992 - Page 29
Rod Grams: Some of it goes below...
Erhart: We11, I'm not asking to hold this up but I think we'd would use
this to tell us.
Al -Jaff: We were out there and.
Krauss: We're a little confused. I mean Rod lives there and obviously
knows the place a lot better than we do but we were convinced that there is
tilling in this corner. And then when we get up on the Ryan piece, I know
that some of that area...
Rod Grams: A lot of that is meadow grass right now. There might be some
tilling...
Krauss: But in any case, there is a substantial amount of land being
reserved so that we not only have green space. Frankly the green space
there, it is not, we're talking about a ditched creek in this area and I
think at some point in time the city's going to want to come in and do tree
planting and whatever else along there.
Erhart: Right, and what you've got to have to do that is you've got to
have enough high land so the trees will live. You can't plant oak trees
and maple trees in a wetland. That's my point here.
Krauss: That is true. But a lot of this area is out of the wetland
proper. It's mostly in the flood plain. 100 year flood plain.
Erhart: I couldn't relate this plan to that and that's why I think it's
important that we get in and we, just like we're doing on TH 5. You know
everybody who lives north of TH 5 wants to get this TH 5 defeined. Well I
want to, for 6 years have wanted to get this Bluff Creek greenway defined
so when we got plans, we could actually compare it to some elevations and
say, okay. Yeah, this is reserved for a future greenway and we're not
going to have people's properties and we may have to buy that land at that
time but today I'm real concerned that we don't know what we're doing and
I can't tell.
Krauss: Well I'd certainly support the idea of the Planning Commission
stating a desire to have a specific plan developed for the corridor. You
know we have gone on record of going to the Park Board and asking for just
that and there is a meeting on June 18th that has, a special meeting that
has to do in part with the potential of a golf course. But the other part
of that agenda is Lance Neckkar from the University who's worked with
Bill Morrish and us on the TH 5 matters, did a design for a Bluff Creek
Park that was featured at the Minneapolis Art Center. I have not seen it
yet myself but he submitted that for design competition and I'm kind of
hopeful that that's going to get the ball rolling to do just what you're
asking.
Erhart: Yeah, that's my concern. In the future when the city, you know we
all talk about preserving open space and to me this is the perfect example
of doing that. In order to get what I envision as a Bluff.Creek Park,
Planning Commission Meeting
June 3, 1992 - Page 36
and 200 years so we're setting a pattern here. I think we've got to really
evaluate where we're going with this tree stuff. So I think that's all the
things I've got.
•
Ahrens: That's it for you?
Erhart: That's it.
Ahrens: Do you have anything specific on the wetland alteration permit or
the rezoning? Sharmin, on page 11. The lot width and page 12 and 13.
There's a number of them that appear to be less than the required 90 feet.
Al -Jaff: Those are on cul -de -sacs. If you take the setback of 30 feet,
then you would meet the 90 foot width required by ordinance.
•
Ahrens: Okay, so every single one of these that's under, it goes on page
14 and 15, it seems like a lot of lots here. I count 29 lots.
Al -Jaff: They're either on a cul -de -sac or on a curve and the ordinance
allows it.
Ahrens: Okay. Do you have a condition in here, maybe I just missed it
about the applicants demonstrating to the staff that a house and deck can
be placed on those two lots?
Al -Jaff: It should be in the preliminary plat.
Ahrens: Maybe I missed it. '
Krauss: We believe there was one that probably dropped out in the editing u
process. There should be one.
Ahrens: Okay, and that should be in there?
Krauss: Yes.
Ahrens: And also I think we should have a condition that all driveways in
the development not exceed 1O% grade. This seems to be an issue with
several of the driveways right?
Al -Jaff: It's in condition number 11. .
Ahrens: Okay. Is there a question for any of the other lots besides Lots
25 and 26? Maybe we should just in general put. Because it's not just
those two lots we're concerned with. It's any lot in the development.
Al -Jaff: Correct.
Hempel: It appeared based on the contours that they provided that those
were the only two lots impacted at this stage but if further modifications
are done, so it's known that 10% is our maximum grade.
Ahrens: On page 6 of your report, Sharmin you talk about protective
measures being implemented for using snow fences and other means during the
I . Planning Commission h-c,.ing
June 3, 1992 - Page 37
II construction period. Do you have that in there? On page 6, your second
full paragraph?
II Al -Jaff: I don't have it as a condition of approval.
Ahrens: And it should be. I have kind of a cryptic note in my notes here
I and I'm not sure what I'm talking about but someplace in your report you
talk about redesigning and raising lot grades to minimize runoff toward
Audubon Road. That's in here as a condition? If not, it should be.
II Hempel: Condition number 11, I think one of the sentences could be
expanded.
II Ahrens: Pardon me?
Hempel: On condition number 11, midway through it. The applicant shall
I amend the grading plan for Phase 1 to accommodate future upgrading of
Audubon Road. That's where it was implied the back yards should be graded.
II Ahrens: Maybe we should make it more specific because the concern seems to
be pretty specific about the runoff. I agree with everyone here who said
there should be no variance. I think that's a good idea. The driveway
access, I think we should somehow try and have a driveway access there. I
I don't think the main goal of the city is just to make sure that cars travel
as quickly as possible down roads. As long as we're building residential
neighborhoods along collector streets, I think that we should be concerned
I with what they look like and how liveable they are and the character of the
city.
Erhart: I didn't follow your recommendation.
II Conrad: What'd you say?
I Ahrens: That there should be a driveway. We should allow a driveway.
Conrad: A curb cut?
II
Ahrens: A curb cut, yeah. A driveway out to Audubon Road.
Erhart: Just leave it the way it is.
II Emmings: Single or U?
I Ahrens: It doesn't matter to me. I mean whatever can be worked out with
the engineering department. I don't see that the horseshoe, it hasn't been
proven to me that that's a dangerous situation so.
II Emmings: Has it been proven that it's safe? I mean in his opinion.
Hempel: It may be safe at this time but we're looking long range down the
I road. Down the way as the road capacities are reached.
Ahrens: But also as the road capacity is reached, the traffic slows down
1 right?
II
Planning Commission Meeting
June 3, 1992 - Page 38
Hempel: The speed limit changes, yes. Typically it probably would in
P P 9 Y YP Y P Y that
area somewhat. Still there'd be some concerns with turning movements into ,
the driveway and so forth.
Ahrens: How many trips a day do you think Mill Street has down at
Excelsior? Where CR 17 ends up. And there's curb cuts all along that
street. There doesn't seem to be any problem. They get a lot of traffic."
You know what I'm talking about?
Krauss: They also have lots of speed traps along there. '
Hempel: 30 mph I believe too.
Ahrens: 30 mph, yeah. Okay. I don't have anything else. Is there a
motion?
Conrad: Let me ask one more question because I'm confused about the trail"
on Audubon. On this parcel. Where is the trail on Audubon?
AI -Jaff: West off Audubon Road. '
Conrad: Okay, it's close to the tree.
Erhart: On the street? ,
Al -Jaff: It's part of the public right -of -way. It's not on the property
ar: - '--ndscaping is being installed on the property.
A Kind of like Lake Lucy Road.
C And is that the way we've been doing trails? That the city has 1
been ceveloping the trail?
Krauss: It's actually been a combination of either it's in the right -of- I
way or occasionally there's a separate easement provided. Within the
downtown sidewalk system and Market Square here is not going to be in the
public right -of -way. It wasn't originally in the public right -of -way. It '
was in an easement, off street. It's really a matter of how wide the
right -of -way is and can we accommodate it within it. In this case we can.
Conrad: And who's responsibility has it been to build the trail? '
Krauss: We have done it with public improvement projects.
Hempel: As we upgrade the section of street to urban standards, we would
include the trail section at that time. In some cases however we have mad
the developer actually go back. Or include it in his project to build it
at this stage.
Conrad: I have a recollection that we have done that. So we are doing it I
two different ways.
Hempel: I believe in this area because it's kind of a piece meal, we have
development down here. We have no development up here yet so you're going ,
II , Planning Commission
June 3, 1992 - Page 39
to have a stranded piece of trail out here with no connection inbetween. I
think that's where staff believes that the trail system will be built under
' an improvement project with the upgrade of Audubon Road.
Erhart: At 50 feet it'd have to be on street right?
' Hempel: It would be within the street right -of -way, yes.
Erhart: It would be on the inside of the curb.
Hempel: It would be between the curb and the property line.
' Erhart: Oh it would be on the outside of the curb like a sidewalk then?
Hempel: That's right. Typically it falls one foot inside of the property
line on the right. One foot towards the street.
Erhart: 50 feet gives you adequate?
' Hempel: Yes.
Emmings: Mr. Grams has left and don't we have a standard condition that in
the year an approval is given to a plat, the applicant has to declare
' himself a Democrat? Haven't we used that before?
Ahrens: That was one of the conditions that was left out too.
Emmings: We'll add that in.
' Ahrens: Steve, you're making a motion right?
Emmings: Sure. I'll approve that the Planning Commission recommend the
City Council approve Wetland Alteration Permit #92 -6 with the conditions
contained in the staff report.
Conrad: I second.
Emmings moved, Conrad seconded that the Planning Commission recommend
approval of Wetland Alteration Permit *92-6 with the following conditions:
1. All wetland areas will be protected during construction by Type III
erosion control. All erosion control shall be maintained in good
condition until the disturbed areas are stabilized.
2. The wetland area remain undisturbed.
' 3. The applicant shall receive a permit from the Watershed District.
4. The applicant shall meet all conditions of the Subdivision #92 -5 and
' Rezoning #92 -3.
All voted in favor and the motion carried.
Ahrens: Motion on the Rezoning.
Planning Commission h,eting
June 3, 1992 - Page 40
Conrad: I move that the Planning Commission approves Rezoning 092 -3
property from A -2 to RSF per the staff report's two conditions.
Erhart: I'll second.
Conrad moved, Erhart seconded that the Planning Commission recommend
approval of Rezoning 192 -3 property from A -2 to RSF with the following
conditions:
1. The applicant shall enter into a development contract containing all oil
the conditions of approval for this project and shall submit all
required financial guarantees. The development contract shall be
recorded against the property. ,
2. The applicant shall meet all conditions of Subdivision #92 -5 and
Wetland Alteration Permit #92 -6.
All voted in favor and the motion carried.
Ahrens: Do we have a motion on the Preliminary Plat? '
Emmings: I'll move that the Planning Commission recommends the City
Council approve Subdivision #92 -5 as shown on the plans dated May 4, 1992 II
subject to the following conditions. I'll stop right here and emphasize
that I'm striking the language granting a variance. It will be all the
conditions in the staff report. With regard to condition number 6, that
deals with the driveway for Lot 8 going out to Road E over Lot 7. I would
move that that language be retained in here with the understanding that we
feel that it may be appropriate for the character of the property to have a
driveway of some kind going out to Audubon Road, but that it will be the '
burden of the applicant to get to the City Engineer and see what they can
work out between now and the time of the City Council hearing. With regard
to condition 11. Joan raised an issue that I didn't understand with regar'
to runoff. Making something more explicit about runoff going out to
Audubon Road and I want that one changed to be more specific to take into
account the comments that she made, which will be in the record. There
• will be an additional condition number 16, that between now and the time ot,
the City Council hearing the applicant should work out with city staff
whether or not Lots 10 and 14 in Block 2 are in fact buildable. And then
an additional condition number 17 related to the language on page 6 of thell
staff report having to do with trees designated for preservation as was
also pointed out by Joan.
Erhart: Before someone seconds. I have a question. The last one on the II
tree conservation easement. That's what Steve?
Emmings: That's on page 6. The second full paragraph be added as a
condition that the trees designated for preservation shall be protected by II
snow fence.
Erhart: Could I ask you to change 7(d) where it says conservation '
easements over all designated tree preservation areas to conservation
easements over areas as designated by staff. Would you agree to that?
A Planning Commission hdecing
June 3, 1992 - Page 41
Ahrens: What's the point of the change of language?
Erhart: Because now you're requiring essentially to have a conservation
easement over every colored area on this map. And Paul's already said that
he doesn't plan on doing that.
Krauss: And I think that's mentioned in the staff report too.
Emmings: Okay, that's what I meant.
' Erhart: Alright, then I'll second it.
' Emmings moved, Erhart seconded that the Planning Commission recommend
approval of Subdivision *92 -5 as shown on the plans dated May 4, 1992 and
subject to the following conditions. .
' 1. All storm sewer drainage pipes should be designed for a 10 year
frequency storm utilizing a rational method. Storm drainage retention
pond, detention areas and outlet piping shall be designed for a 100
year frequency, 24 hour single event using the "SCS Method" established
for use in Minnesota. The discharge rate shall not exceed the
predeveloped runoff rate. Ponds shall also be designed to "NURP"
' standards. All storm retention ponds shall be constructed to NURP
standards.
2. All utility and street improvements shall be constructed in accordance
' with the current edition of "City's Standard Specifications and Detail
Plates ". Detailed street and utility construction plans and
specifications shall be submitted for City Council approval.
' 3. The applicant shall apply and obtain permits from the Watershed
District, DNR and other appropriate regulatory agencies and comply with
their conditions of approval.
' 4. Watermain systems shall be designed to ensure adequate fire flow for
the site. Design calculations shall be submitted to the City Engineer
' to verify pipe size.
5. The applicant shall enter into a development contract with the city and
' provide the financial security to guarantee compliance with the terms
of-the development contract. The final plat shall be contingent upon
the City Council authorizing and awarding a public improvement project
for the extension of trunk sanitary sewer and water facilities to
' service the site.
6. All lots shall access from interior streets and not Audubon Road.
' Street grades shall not exceed the 7% maximum street grade per City
ordinance. A deceleration /acceleration lane shall be provided on
Audubon Road. The center island shall be deleted from the southerly
access street (Road E). The existing driveway to the site shall be
relocated to access from the northerly loop street through Lot 7, Block
2. A cross access easement shall be convenyed to Lot 8, Block 2 with
the understanding that the Planning Commission feels that it may be
appropriate for the character of the property to have a driveway of
Planning Commission ' ing II
June 3, 1992 - Page 44
some kind going out to Audubon Road, but that it will be the burden of
the applicant to get to the City Engineer and see what they can work
out between the Planning Commission and City Council meetings.
7. The final plat shall be amended to include expanding the 15 foot wide II
drainage and utility easements to 20 feet wide and extending the
drainage easements through Lots 12 and 13, Block 1. The following
easements shall be provided:
a. Dedication of all street right -of -way. ,
b. Conservation and drainage easements over all protected wetland and
ponding areas. Provide access easements to allow the city to
maintain all ponding areas. '
c. A 20 foot wide utility and drainage easement over all sewer, water
and storm sewer lines located outside public right -of -way.
d. Conservation easements over areas designated by staff.
e. Standard drainage and utility easements along each lot line. '
f. Dedication of Outlot A to the City.
8. All necessary permits shall be obtained from the pipeline company for I
any grading or construction activity within the pipeline easement.

the subdivision in accordance with the Fire Marshal's recommendations.
10. All areas disturbed during site grading shall be immediately restored
with seed and disc - mulched or wood fiber blanket within two weeks of
completing site grading unless MnDot's planting dates dictate

' Paul Krauss presented the staff report on this item and went through the
City Attorney's Findings of Facts.
' Erhart: In this case, how do you know when you excavated below the water
table?
' Krauss: Well, we looked at the possibility of putting in a single
elevation. A not to exceed elevation but in the City Engineer's opinion,
the ground water elevation was fairly variable across the property.
1 Erhart: A lot of changes.
Hempel: Sample borings can be taken to determine what the water level is
in a specific area there. It's kind of to document the water table. Water
tables do fluctuate with seasons so it is a difficult to pin point a
certain elevation. You do receive modeled soils after just a couple feel
1 underneath the surface in some areas in fact. So it is a difficult answer
to give at this point but we feel by random borings to determine the water
table would give us a significant benchmark if you will.
